With your posted data in columns A and B...

AND
C1: PAYMENTS

Then this formula returns the sum of
Col_B amounts corresponding to PAYMENTS:
D1: =SUMIF(A1:B5,C1,B1:B5)

Does that help?

I think that this is an easy question but I simply couldn't find the
answer.

I have the following list in XL2003

Column1 Column 2
PAYMENTS 100
CREDIT 200
PAYMENTS 1000

I want to create a formula somewhere in Sheet1 that will produce me the
equivalent of the sum of Column 2 where Column1=PAYMENTS. In other wants
the SUM of PAYMENTS is 1100. How can I access this sum using a formula
somewhere in my worksheet.

Thanks
Michael
