Hi All,

I have to say I'm pulling what little hair I have out over my SUMPRODUCT formula.

Can anyone advise what I am doing wrong with the formula below? Basically I am trying to Sum column AA based on two conditions in Col H and Col S.

When I enter the formula i get the #NUM! error?

=SUMPRODUCT(--(Sheet1!H:H="LN"),--(Sheet1!S:S="Garry"),Sheet1!AA:AA)

Thanks everyone.
Garry
