I have the following data set:

A1 B1 C1
ControlTotals Account Amount
Development 100001 $50
Communications 100002 $70
Communications 100001 $75
Operations 100001 $1,115
Control Total 100001 $101,530

And the following formula:
=SUMPRODUCT(--($A$2:$A$1000="Control Total"),--($B$2:$B$1000="100001"),C$2:C$1000)

Is there a way to manipulate this formula to sum all of the 100001 Amounts and NOT the amounts with "Control Total" in column A?
