I am trying to count all instances where Data!K7:K9999 = The option in
Monthly Summary!A10 when the date in Data!AE7:AE9999 = Data!$C$1

This is not adding up. See below for my formula. It returns Zero, it
should be returning 2.

Thanks for your help


=SUMPRODUCT((Data!K7:K9999='Monthly Summary'!A10)*($C$1=Data!AE7))
