Hi everyone,

I'm using
=SUMPRODUCT(--(Data!$C$2:$C$10000=$A5),--(Data!$K$2:$K$10000=10),--(Data!$I$2:$I$10000="M"),--(Data!$AC$2:$AC$10000="c"))+SUMPRODUCT(--(Data!$C$2:$C$10000=$A5),--(Data!$K$2:$K$10000=10),--(Data!$I$2:$I$10000="M"),--(Data!$AC$2:$AC$10000="m"))

So it counts if C = a5, K = 10, I = M and AC = either c or m

Is there a better way to do it?
