Sorry ...there was a typo.

See Bob Phillips' reply for explanation of SUMPRODUCT.

=Sumproduct(--(A1:A100="Regular"),--(C1:C100="A"),--(B1:B100))

Thanks HTH and Bob. I tried the SUMIF and it works. But not sure I understand
sumproduct. I am new to excel here so please bear with me.

What is -- in the formula? Excel does not take this. I tried using copy /
paste. Can you please elaborate?

Thanks.

I have data in the following format

Resource Type Resource Project
Regular 10 A
Regular 20 A
Contractor 05 A
Regular 10 B
Contractor 15 B


How would I find the sum of all resources (regular and contractor) for
project A, B, C etc. Which formula do I use? And then sum of regulars for
project A, B, C etc.

Thanks.
