Hi everyone,

Could you help me? I can't figure out what is wrong with my codes. I tried using this on some data on Excel.

What I am trying to do is to get percentages from data arranged into 2 columns and 10 rows (and this is done for 3 sets of data). I have no problem with that.

What I have problem with is the nested IF loops. The data runs through the first IF and ELSEIF while ignoring the other ELSEIFs.

Got a workbook that you can post?

Impossible to give you concrete ideas without seeing at least dummy data.

Very very difficult to troubleshoot complex logic statements when you don't use option explicit.

You could definitely benefit from some modularization of your code, a la:

You may be able to fix further just by simplifying some of your structure.

Here it is:
http://i625.photobucket.com/albums/t...Testdata-1.jpg

3 sets of data. Each with 10 rows and 2 columns. In this case, all 3 sets contain the same data, but this is not necessarily the case all the time.

The idea is to get the percentage of number in the second row that are smaller than or equal to the first row printed at the bottom. Eventually I will modify it to work with dates i.e. classify by week.

I agree that my codes are very procedural. I could definitely benefit from object oriented-ness but I haven't learnt how to do it in VBA. Furthermore, I'm trying to get this to work as fast as possible. Any clues as to why it's not working?

Having manually typed in your data from the image you posted (instead of an actual workbook)... I get an overflow using your code, and I get some meaningless percentages when I use my code.

So...percentage of what and what? I think you're mixing up columns and rows... but if you're going to post an image of a workbook (rather than the real thing), can you at least post what it should look like at the end result, with maybe a highlight on what numbers are doing what?

And since your code has some pretty complex elseif statements dealing with various scenarios, can you post some less dumb dummy data (i.e., deal with NA, empty cells, etc.). If you're asking the question, might as well get somewhat close.

My second code sample should be able to plug in and do exactly what your current code is doing, with the added benefit that it should be easier to troubleshoot what's going wrong.

Also: if this is some kind of school assignment, this isn't the place to be getting free info.

It's not OOP that you need (although that's good stuff too), just some procedural structure and the benefit of someone pointing out that instead of....
IF x >=1 OR x <8 then
End If

You can simplify a lot by using...
Select Case X
Case 1 To 7
End Select

That makes things a lot easier to read and, more importantly, troubleshoot.

Two suggestions:

1. Post an actual workbook with dummy data, and the cells manually filled in with something close to the end result you want. I am confused by your explanation above.

2. Listen to xld over me as he's much better with Excel than I am. However, I suspect this ends up being more of a general programming question (the subject line is what caught my eye) than something excel specific.

But need an example of an end result or someone smarter than me to decipher what you really want, rather than what you said.
