SUMIF using 2 Criteria in 2 columns

[quailc]

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

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

If Column A = X and Column B = B then Sum all the corresponding value
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 th
same row as the formula.

How can I get the formula to look at the entire array of data an
return the sum of all the column C items that meet the correc
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

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.

I am trying to link my current workbook with:
Workbook name: Leave Planner Apr 06 - Nov 06 working.xls
Worksheet: May 06


=(SUMPRODUCT(1*('[Leave Planner Apr 06 - Nov 06 working.xls]May 06
'!$A$41:$A$68="A&C Cert"),1*('[Leave Planner Apr 06 - Nov 06
working.xls]May 06 '!$D$40="E")*'[Leave Planner Apr 06 - Nov 06
working.xls]May 06 '!$D$41:$D$68))

Thank you
