SUMIF using 2 Criteria in 2 columns

I would be grateful if someone could offer their advice on how to solve a problem I am having with XL.

I am trying to sum all the values in column C if column A and Column B meet the correct criteria.

If Column A = X and Column B = B then Sum all the corresponding values in Column C.

Column A Column B Column C
X B 1
Y B 7
Z C 2
X B 3
Y C 10
(I.e. Answer = 4)

My Excel book quotes the formula below:
I.e. {SUM((A:A="X")*(B:B="B)*(C:C))}

This formula does not look at the whole Column A only the cell in the same row as the formula.

How can I get the formula to look at the entire array of data and return the sum of all the column C items that meet the correct conditions in Columns A &B?

=SUMPRODUCT(--(A1:A200="X"),--(B1:B200="B"),C1:C200)

Note that SUMPRODUCT doesn't work with complete columns, you have to specify
a range.

Bob,

Many Thanks for your advice with this. The SUMPRODUCT function works perfectly! You have saved me an awful lot of time messing around with this.

Kind regards
Corinne

I would be grateful if someone could offer their advice on how to solve a problem I am having with XL.

Is it possible to perform the SUMPRODUCT function on a data range that is in a seperate workbook?

I have tried selecting the range from another workbook but it comes back with #value result.

How do I link the 2 workbooks together for this to work correctly?

Yes you can. Show us what you have tried.
