I need to edit the formulae below to allow the sumproduct use the two arrays.
SUMPRODUCT(SUMIFS('PO1 report'!$AB:$AB,'PO1 report'!$O:$O,$B20,'PO1 report'!$E:$E,E$4,'PO1 report'!$AO:$AO,$A$2:$A$4,'PO1 report'!$G:$G,$A$20:$A$28))
SUMPRODUCT(SUMIFS('PO1 report'!$AB:$AB,'PO1 report'!$O:$O,$B20,'PO1 report'!$E:$E,E$4,'PO1 report'!$AO:$AO,$A$2:$A$4,'PO1 report'!$G:$G,$A$20:$A$28))
