Charlou,

=SUMPRODUCT(--(A1:A3="John"),--(B1:B3="Green"),C1:C3)

Or if you want to have it on another sheet:

=SUMPRODUCT(--(Sheet1!A1:A3="John"),--(Sheet1!B1:B3="Green"),Sheet1!C1:C3)

And the John and Green can also be in cells:

=SUMPRODUCT(--(Sheet1!A1:A3=A1),--(Sheet1!B1:B3=B1),Sheet1!C1:C3)

I am currently using vlookup to put together a summary sheet. However, I
would like to Look up Column A and B, and then return the corresponding
Column C figure. For example:

John Brown 6
John Green 5
John Black 7

If Forename is Column A, Surname is Colume B and Column C is the value I
need to return to the summary sheet. I'm not sure how to lookup more than
one column?

Any ideas??????
