Logical Function Help

Hey all,
I'm still learning how to use all the functions and I need some help. I need to combine two IF statements but can't get the syntax right. The first is easy: IF(A-B>=3,"Don't Count","Count"). The second should basically say: if B=0 and A>=2,"Don't Count","Count". How do I combine those statements? Any help would be appreciated.

You need to define exactly what you want to do, If the first condition is satisfied, i.e A-B>=3 then presumably you want "Don't count" whatever the result of your condition? If so perhaps

=IF(OR(A-B>=3,AND(B=0,A>=2)),"Don't Count","Count")

so that applies "Don't Count" if either condition is TRUE

If that doesn't work for you then try posting some sample data (just a small amount will do) and expected results
