Hi,
I also think it is becouse of regional settings. Now I face problems with
date formulas, probably becouse of regional settings.

Thanks again

Hi

Thanks for the feedback.
Difference in Regional settings for you compared with me in the UK was
the reason you needed to change the commas to semi-colons.
Glad you got it to work.

=SUMPRODUCT(--(Sheet2!$A$$1:$A$1000=A1),--(Sheet2!$F$1:$F$1000=B1),Sheet2!$E$1:$E$1000)

Should be
=SUMPRODUCT(--(Sheet2!$A$1:$A$1000=A1),--(Sheet2!$F$1:$F$1000=B1),Sheet2!$E$1:$E$1000)
