Hi All,

Random question i have a large Excel Workbook (which is protected) and has over five sheets on it - however one sheet has randomly decided not to scroll... yes i know sounds random! If i use the cursor and down arrows the selection just disappears off the screen.
The page will scroll if i filter by one field, but not if i select (All) for all filters.
All other worksheets scroll fine.
Any suggestions?

Thanks in advance.
Cheers Kaite


Right now I have a sports league with 8 teams, I'd like to create a random 7-game schedule where each team plays the other team only once. Essentially this will be a 7-game round robin. However, I'd like to be able to use this for any number of teams and games.

I'd like to do this in Excel, but I can't figure out how to have a randomly generating non-repeating macro with text values in cells.

So right now I have a column of 8 values and need matrix of 7 columns by 8 rows next to it.

I've found this thread that has one for numbers, but I can't figure out how to do it for text values...

Thanks all!

Hi there

Please can someone help me. How do I create an IF formula to find cells where the number of hours in one cell is more than the number of hours in another cell? eg one cell has 0.40 hrs and another has 02.25 hours - I want have an IF formula to say where 02.25hrs > 0.40 then type "FAILED" but I cant overcome the greater than problem on the hours which is giving me the wrong answer.


A previous poster explained what I also need; there were no responses,
so I thought I would try again.

Does anyone know of an Excel template--or a small stand-alone
program--that will calculate the interest/principal breakdown when
payments are varied in amount and frequency? Free or low-cost, please.
I need one that will work on my Mac/Office 2004. I will need to print
out periodic reports.

Here is the way the previous poster described it:
"Excel template: Loan Amortization for random/irregular payments,
figures days
between payment dates.
I have a loan with a variable beginning balance and irregular payments
with
annual large payment. (based on collections)
Would like to enter payment and date.
then Excel would figure days since last payment, interest amount,
principal
amount, Ending Principal balance.
And total interest paid, total pricipal paid
If I change the starting principal, excel would recalculate all
entries."

Thanks very much.




hi guys,

i have a simple spreadsheet where i'm totalling a few values thru a formula. it's similar to this:

=D13*F13

i'm trying to create a funcion that says if d13 * f13 >= 300, i want the value to stay at 300 max and at the same time, if d13 * f13 < 300, i want the total to remain whatever it is.

i have been able to create both of these formulas successfully by themselves but i can't combine them. is this possible?

any help would be greatly appreciated!!


I'm sure this has been addressed before, and I'm sure one of you 50lb heads has the answer I'm looking for. I want to generate a bank of 200-300 questions in excel and be able to make a test of 50 questions that will be different every time. I want to be able to do this with multiple choice questions as well as just plain essay questions. Can I have some instruction or examples? Thanks guys!


I am trying to correct a formula for a productivity worksheet in excel. The idea is that we would have the ability to input the number of hours worked each day and the number of direct hours (working with clients) per day. Then take the daily percentages and add them then devide them to determine the final productivity percentage for the week. Additionally not everyone works a full week so I would need it to only divide the percentages of the days that were completed. Any suggestions? or does anybody know a formula that would accomplish this already? I am good with basic excel and was able to identify a flaw in the current productivity sheet.


I have looked over the forums for information on how to do this, and can not find anything. I have used conditional formatting to identify duplicates in my spreadsheet. I have a unique user ID, which combines the first and last name fields into one. However, in 10,000 there are a number of John Smiths, Joe Adams, etc. With smaller lists, we search manually, and then add a 1, 2, 3, etc to each duplicate to create a unique value for the User ID.

My question is:

Is there a way to check for duplicates, and then automatically add numbers to the duplicate values to make them unique? If so, how can this be done?

So that you will have this:

JohnSmith
JohnSmith2
JohnSmith3
JaneDoe
JaneDoe2
JohnAdams
JohnAdams2
JohnAdams3
JohnAdams4

I think I have done a good job in illustrating what I would like to be able to do, but if there is still something that is unclear, I will post whatever clarification is needed.

Thank you in advance for your help!!


Sorry for the question. Normally I find answers to my excel questions by going through the help tab or by searching on Google. However, I don't even know what question to ask on this one!?!

Basically I have created a spreadsheet with several columns, but I have one column that lists the shirt size (YS, YM, YL, AS, AM, AL, XL, 2X, 3X) of each person. Is there a formula that I can create that will tabulate the number of sizes (i.e. AS=2, AM=7, etc.)?

In previous years I made a column for each size, and simply placed a "1" in the correct column, and had excel just add the 1's from each column. However, that takes more time and space. I was hoping to streamline it this time around.

Thanks for taking the time to read this post. Any help would be appreciated! Thanks, doug


Good afternoon,

Is there a way to enter a colon into a standard number to create a value that can be formatted into a 24 hour time value ?

eg a time is listed as 1345 with a general number format, and I want it returned as 13:45 witha custom format of hh:mm.

Other than creating a table and using a vlookup function, I am hoping there is a better way?

How do I calculate the number of batches per hour? Here's what I have so far:

Cell B5: start time: 4:15 formatted as 4:15:00 am
Cell B6: finish time: 6:15 formatted as 6:15:00 am
Cell B7: total time: 2:00 formula in cell: =TEXT(B6-B5,"h:mm")
Cell B8: total batches processed: 22 (this is entered manually)
Cell B9: batches per hour: formula in cell: =B8/TEXT(B7,"h")

as long as I have this formula in cell B9 the answer comes out correct which should be 11 per hour.
If the formula in B9 is B8/B7, the answer is 264.0, Is this because of the way excel is reading the total time or the total time is formatted as a time, not an actual number? Is this the correct way to solve the problem?
answer should be 11 per hour.


I have AplphaNumeric part numbers that sometimes contain hyphens or decimals. In order to make them more searchable (since people don't always use the hyphens or decimals properly when they search) I would like to create all the possible variants of the part number, but with one formula.

So AHW18.787 becomes AHW18 787 and AHW18787 with

=SUBSTITUTE(A1,"."," ") and
=SUBSTITUTE(A1,".","") respectively, and

AHRTW-A18-7007 becomes AHRTW A18 7007 and AHRTWA187007 with

=SUBSTITUTE(A1,"-"," ") and
=SUBSTITUTE(A1,"-","").

What I need to be able to do is merge these formulas into one, so that no matter what format the part number is in A1, I get a version of it with spaces in B1, and a version of it with no spaces in C1. I just have not been able to nest it all together - is it even possible with this command?

Thx


I have an excel worksheet that adds two other worksheets in a data
triangle. I copied it to create a new data set and used find &
replace to change the worksheet references to the new ones.

The cells still contain the result of the old formula referring to the
previous worksheets. The only way I can get the formula to return the
correct result is to edit (F2) each cell and press enter. Calc now
(F9) does nothing.

I've seen this before, but this time, I need to calculate many
thousands of cells and don't have time for this workaround.

Any ideas?

Thanks.

I feel like this should be really easy and I am just out of it today but I cannot figure this out. I want to lock a row and filter (with filter,not sort, tool) the other rows. I attached an example

The row in RED I want to never be changed or added in the filter, but I want row 2 and 1 to filter together. So I want (in this case) the flavor to filter with the same number. SO i guess the filter process would be dependent upon the total number of votes. Any ideas? Thanks!

I had to create the information in tables and went from there. Got it. Thanks!


Hi, can anyone help me with the below...

Im looking for a vlookup formula which will give me the maximum number from a list which contains multiple matches, i.e.

Lookup number 1 from column A, then give me the largest number from column B

example table:
A B
-----
1 5
2 2
1 11
3 2
4 5

the result would be 11

thanks all!


Hi All,

I am trying to make excel automatically add a leading zero to values which are 5 digits long;

i.e. number input is 15185, then excel automatically changes it to 015185.

If I put a Customer Number Format of 0##### it works, however, a user could put any length of number into these cells, and if the number is less than 5 digits I don't want a leading zero.

Is there any way of writing a small macro to sort this out.

The numbers would be input into range B16:223.

Many thanks,


Andy


Here's my formula... =SUM(S7)-T5

If that number is less than -100, I want it to show as blank.

Any help?

Right now, I'm trying to accomplish this by making a conditional format...meaning when my cell equals less than -100 I make the cell color and font the same (so it looks blank, but its not). When I print it, it still shows the negative value.


Thanks.


Hello from sunny Madrid

I have created a complex formula to help me calculating Golf handicaps for players.


The formula is in the first cell and I want to drag the formula across to the right to cover the 18 holes.

But ALL the values change and I want some to change and some to stay constant.



How do I tell excel to drag the formula across but keep certain parts of the formula the same..ie ....=D11.... in the formula when dragged across doesn't go D12,D13;D14 in each cells formula and should stay as D11 for all.

Many thanks for your help

Hello, I'm trying to count the number of times a name appears across multiple worksheets but I can't seem to figure it out.


I have 6 sheets to count and all the names are in column A (from A1:A100) on each sheet. The names are not in a particular order.

On sheet 7 I want to have a cell beside each persons name that counts the number of times their name appeared on the other 6 sheets.

For example Sheet 7 (called total) would have

Joe 5 (where 5 is the outcome of the formula I'm looking for to count all the times "Joe" appears on sheets 1-6).

I have it counting per sheet with =COUNTIF(A1:A130,"name") but this is not quite what I am looking for.

Thanks in advance for any advice.

Ok, guys, new to this forum and I need some help with a business invoice. I know how to create a drop down list. But what I want to do is create a Drop-Down list with customers names, say cell A11. After selecting a customer name from the list, It would be able to populate the address in cells A12 and A13. Is this possible?

Thank you in advance,

From limited experience I know that excel calculates dates via serial numbers.

I have formulas to add a number of days to a cell containing an entered date and display the resulting new date (ie. 03/01/2011 (c34)+11 = 03/12/2011)

I am seeking to leave resulting formula cell blank until a date is entered in the input cell. Currently when the input cell is empty the formula cell obviously displays 1/11/1900 using the above example.

What conditional format would achieve leaving the formula cell blank until date data in entered into the source cell?

Hopefully a simpler question for your experience level than mine.


Hello

I'm quite experienced Excel user. I've never come across this problem but tinkering in every conceivable way within Excel settings and the solution has eluded me.

I have added a worksheet created elsewhere (it is a form I need printing, with the data coming from 2 sheets I have created from scratch) which has pre formatted cells for Date and Client Name etc.

When I try to reference the cell in this added sheet from my 2 sheets, instead of the result, it always displays the formula, not the result.

I have tried doing it from one of my sheets to reference to this new, and that displays the result and not formula. I can't imagine why it's doing this and I've never seen it happen before.

Formatting cells, giving cells names rather than the usually adequate of reference to the Cell Number doesn't change things. I wonder if I've picked up some legacy protection from the original form but can't see anywhere in the tools etc that's obvious.

There's about 50+ cells that need referencing and I got to get this done for work.

Please help me. This is my first need to post on a Excel Forum as I've always found help or answers from other peeps or internet but this one is making me scratch my head big time.



I have an extensive spreadsheet with several columns and all showing borders
where each cell/column begins and ends. However there are a few cells where
the break with the next cell does not show the line.

I have highlighed the cell in question, gone to format/cell/borders and
everything looks fine. Black color + format border shows square with all
sides of square showing.

Any thoughts on how to fix these few random cells.

Thanks
