I'm trying to do a somewhat complicated find in VBA.

I have a worksheet with column B having only two different values (eg. a

(eg. 1 and 2). The values that I want to return are in columns E and F.


So what I'm trying to do is this:

If columns B and C equal "a" and "1" (respectively), then subtract the
values in E and F (on that row where the columns equal) and return that
result on another worksheet.

Repeat for all the different combinations...a1, a2, b1, b2.

To illustrate:


Code:
--------------------


Column B | Column C Column E | Column F

a 1 70 50
a 2 80 30
b 1 60 20
b 2 40 20


--------------------


I want to find a1 and write "20" in another worksheet.

Sorry if this is an overly long explanation, I feel like it's confusing
to explain. Let me know if anything needs to be clarified. As always,
any help is appreciated!

How long is your list? Is the data contiguous? Do you want to store
the result in the same row on the other worksheet?

Setting those questions aside I'd suggest either a FOR/WHILE loop. I
suppose there are more elegant methods and most experts try to avoid
loops but they can be quite fast for a simple operation like this and
the code is easy to understand.

For i = first_row to last_row
if cells(i, "B") = "a" and cells(i, "C") = 1 then _
worksheets(othersheet).cells(i, "A")= cells(i, "E") - cells(i, "F")
Next i

This all assumes I understood your question and there are several
details to check to meet what you really have to work with.

John,

You understand what I'm trying to do. To answer your questions:

How long is your list?
401 rows, but that may change (I'd rather not hard-code it)

Is the data contiguous?
Yes

Do you want to store the result in the same row on the other worksheet?
I need to store the results in the same column, but different rows.


Your solution so far makes perfect sense.
I tried modifying this part for my code:

For now, can we just select the row where it finds those two values? I want to see that it works, and I'm not sure how to do that.

I'm also having a problem with what it's supposed to equal to since those values are not the only values in the cells. It doesn't just say "a" in the column I'm searching for. It says something like "a 2342 332" and it doesn't just say "1" in column C, it says "abcdefg (1bb)." Point is, I have more than just the string I'm searching for in the cells. Do you know how I can use wildcards in the search? Thanks, you've been really helpful so far!

As usual there are many ways to address the next requirements for
testing the cell contents as you describe below. But the simplest
solution I would use would be to test the cell to see if it contains
"a" or "1" by using the instr function like this:

For i = first_row to last_row
if instr(cells(i, "B")',"a")0 and instr(cells(i, "C"),"1")0 then _
worksheets(othersheet).cells(i, "A")= cells(i, "E") - cells(i, "F")
Next i

The second line in the loop will store your result in the same row on
the target sheet as the source sheet.

For only 400 lines of data the for loop will be very fast.

John,

Perfect! It does the calculation and writes it on the source worksheet.

Now, how can I get it write to another workbook? This one may be a bit tricker, because the workbook I want to write to doesn't always have the same name (it is always open though). This is how it is written (and working) for my other sheets:

When I tried to implement this code into yours, it was posting a value of 0, probably because it lost the values when I switched sheets. Can I store the answer in a variable and then call the variable to write the answer in the cell?

Update: tried it again, it works!

Thanks so much for your help John!

Change this line (to the equal sign):

worksheets(othersheet).cells(i, "A")= cells(i, "E") - cells(i, "F")

to something like:

workbooks(ws.Name).activesheet.ActiveCell.FormulaR 1C1 =

You may need to tweak this a little but basically you need to
reference the workbook, then the worksheet and then the cell.

John,

One more question. How do I get it to loop through all the sets of criteria and put it where I want it to go? For example, I want "a1" to go into cell C3, "a2" to go into cell C4, "b1" to go into cell C8, "b2" to go into cell C9, etc. I can do it with one set of criterion (like "a1"), but how do I combine it with all my criteria?
