I want to calculate a running subtotal on a row by row basis, which is easy enough using:
=SUBTOTAL(9,$AT$3:AT4372)
but I want to base this subtotal on certain criteria from other columns, so I want to effectively say something like:
=SUMIFS($AT$3:$AT$4372,$AT$3:$AT$4372,SUBTOTAL(9,$AT$3:AT4372),$G$3:$G$4372,$G206,$I$3:$I$4372,$I3)
so the subtotal will only update based on the criteria in Colmuns G and I, how could I go about doing this as my approach is clearly wrong?
Many thanks
