Hope this will help you.

=IF(ISNA(MATCH(E7,Sheet3!$F$6:$F$14,0)),IF(ISNA(MA TCH(E7,Sheet3!$G$6:$G$14,0)),IF(ISNA(MATCH(E7,Shee t3!$H$6:$H$14,0)),"","Lot 3"),"Lot 2"),"Lot 1")

in sheet 1, copy below formula to column g8 to o10

=SUMIFS(Sheet2!$F$7:$F$28,Sheet2!$D$7:$D$28,Sheet1 !G$7,Sheet2!$G$7:$G$28,Sheet1!$F8)

Hi

In G8:

=SUMPRODUCT(SUMIFS(Sheet2!$F$7:$F$28,Sheet2!$E$7:$ E$28,Sheet3!$F$7:$F$14,Sheet2!$D$7:$D$28,G$7))

Replace the highlighted range accordingly for Lot 2 and Lot 3.
