I manage to get what I wanted with a complicated "uncompressed" formula (like a DivX compared with AVI uncompressed). The formula was something like this: =SUM(AND(G7=$F7)+AND(G8=$F8)+AND(G9=$F9)+AND(G10=$F10)+AND($F11=G11)+AND($F12=G12)+AND($F13=G13)+AND($F14=G14)+AND($F15=G15)+AND($F16=G16)+AND(G17=$F17)+AND(G18=$F18)+AND(G19=$F19)+AND(G20=$F20)+AND(G21=$F21)+AND(G22=$F22)+AND(G23=$F23)+AND(G24=$F24)+AND(G25=$F25)+AND(G26=$F26)+AND(G27=$F27)+AND(G28=$F28)+AND(G29=$F29)+AND(G30=$F30)+(AND(G32=$F32)*AND(G32<>0))+AND((G33=$F33)*AND(G33<>0))+AND((G34=$F34)*AND(G34<>0))+AND((G35=$F35)*AND(G35<>0))+AND((G36=$F36)*AND(G36<>0))+AND((G37=$F37)*AND(G37<>0))+AND((G39=$F39)*AND(G39<>0))).
Ugly, isn't it? But was that I was looking for. Lucky me I just needed only 30 rows to count, otherwise I'm pretty sure that this formula will not work if it was larger.
Anyway thanks for your advices. Macros I don't know to use.
