=SUM((A2:A7=D1)*(B2:B7=E1)*C2:C7)

But press ctrl+Shift+Enter rather than just enter by itself to set the formula

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 :-)
