if you are using excel 2007 enter
=sumproduct(--(D1=A:A),--(E1=B:B),C:C)

If you are using XL2007, I would you use a built-in function call SUMIFS()
rather than use SUMPRODUCT()

=SUMIFS(C:C,A:A,D1,B:B,E1)

Hi,

I need to lookup values in two columns and where matches are found, SUM a
numeric in a third column. The below data probably explains it better:-

A B C
Name yes or no Total
Joe yes 7
Adam yes 1
David yes 5
Joe yes 3
Joe no 4
Adam yes 3

D1=Joe
E1=yes

Where column A ='Joe' and column B='yes' then SUM the content of column C.
So in this case it would return '10' (i.e. 7+3).

Many thanks :-)
