Assuming that there is only one instance of I7 and I2:

Entered as an array using the key combination of CTRL,SHIFT,ENTER (not just
ENTER):

=ADDRESS(MAX((Inventory!A4:A3500=I7)*(Inventory!B4 :B3500=I2)*(ROW(Inventory!D4:D3500))),4)

I have the formula listed below running and I want to insert a column next
to
it to locate the cell that the results come from.

=SUMPRODUCT(--(INVENTORY!$A$4:$A$3500=I7),--(INVENTORY!$B$4:$B$3500=I$2),(INVENTORY!$D$4:$D$35 00))
