Try this...

=SUMPRODUCT(--(A2:A6="Voice"),--(B2:B6="DMS250"))

Better to use cells to hold the criteria:

D2 = voice
E2 = DMS250

=SUMPRODUCT(--(A2:A6=D2),--(B2:B6=E2))

If you're using Excel 2007:

=COUNTIFS(A2:A6,D2,B2:B6,E2)

I am trying to determine the formula to count - only if the criteria in two
(or more) cells is true.

Example Data Set

Service Equipment
Data ATM
Voice DMS 250
Voice DMS 300
Data FR
Voice DMS 250

So i am looking for something to show how often both the serivce and the
equipment criteria meet the desired output.

I tried writing a formula like =COUNTIF(A2:A6,"Voice")AND(B2:B6,"DMS250")

where it would then count the data set and report the value of 2 ... 2
times
the criteria is both voice and dms250.

Any thoughts???

Thanks
