Have you tried this:

=SUMPRODUCT(--(Data!$C$2:$C$10000=$A6),--(Data!$S$2:$S$10000=1) ,--
(Data!$K$2:$K$10000<"N2"),--(Data!$K$*2:$K$10000<"N1"))

?

Hope this helps.

Hi everyone,

I'm using the following

Which works beautifully but I also need to say that if k2:k10000 does not
equal N1 it shouldn't be counted as well.

Grateful for any help
