Trickey SumProduct with Multiple Conditions

[Benjamin]

=SUMPRODUCT(--(A1:A24="Ted"),--(B1:B24="May"),--(C1:C24))
column a <Person>, column b <Month>, Column C <Cost>

I need to total all of Ted's Costs for May.
But Now I need to do it for the quarter.
So for say January, Feburary, March and April, four month blocks.
How would I tweak Sumproduct to do that ...
All cost for those four months.

 

[T. Valko]

List the month names for the quarter in a range of cells:

E1 = Jan
E2 = Feb
E3 = Mar
E4 = Apr

F1 = Ted

Then:

=SUMPRODUCT(--(A1:A24=F1),--(ISNUMBER(MATCH(B1:B24,E1:E4,0))),C1:C24)
