I have a three worksheets in this problem However I only
need to get
work with two of them. Here is what I want to do.

Sheet1
ColA ColB ColC

Sheet2

ColA ColB ColC

I want to match the data on Sheet2 ColA with the data on
Sheet1 ColA
However the information to match could show up multiple
times on
Sheet2 ColA

so it could be in row 1, 2, 3 but only in row 1 on Sheet1
ColA

So if Sheet1 ColA matches Sheet2 ColA (anyrow) I want to
add the data
in Sheet2 ColB (whatever row matches) to Sheet1 Col C Row1

Does that make sense?

Not sure if I got the right picture in my head, but I'll
give it a shot. I am assuming when you say "add the data"
you are working with numeric data. You should be able to
do this with a fairly simple function: SUMIF()

Try this: In Sheet1, cell C1 use the formula:
=SUMIF(Sheet2!A:A,A1,Sheet2!B:B)
And copy it into the entire column C - if I understand
your problem I think this should work
