If I wish to search gross sales and return amount for current month (May’17), so formula in Cell B5
=SUMPRODUCT((MONTH($F$3:$F$8)=$B$1)*(YEAR($F$3:$F$8)=$C$1)*($G$3:$G$8="BOOKSTORE")*($I$3:$I$8))

What if I wish to search gross sales and return amount for Year to date (May’17 – Jun’17), which formula I should insert in cell B11?

Please help and thanks in advance.
