But when i use this formula
=sumproduct(Table2!C1:C * (Table2!B:B={"Product x", "Product y"}) * Date range)
it works. Anyone can help to fix my syntax?

I need to sum value of my Revenue of Product Group A within Date Range 1-2 Jan. What formula should I do?
I have tried
=sumproduct(Table2!C1:C * Table2!B:B=filter(Table1!B:B,Table1!A:A = Product Group A) * Date range) '
But it doesn't work.
