I am looking to write a formula, but I'm stuck.

I have a three columns: Project Name, division, phase. I want to write a
forumula that counts the number of projects per division per phase. For
instance, I want to know how many projects are in the AppDev division that
are active. Likewise, I want to know how many Telecom projects are
inactive...etc.

I've tried Count and CountIf functions, but I'm not getting the result that
I want.
How do I go about calculating this?

Thanks
John
