Hi Max,

Yes it works beautifully. I'm going to attempt to work out how it does it
but it may be a long job. Food for thought!

Thanks again

Another alternative option:
=SUMPRODUCT(--(Data!$C$2:$C$10000=$A5),--(Data!$K$2:$K$10000=10),--(Data!$I$2:$I$10000="M"),--(ISNUMBER(MATCH(Data!$AC$2:$AC$10000,{"c";"m"},0)) ))

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

Is there a better way to do it?
