I have "Y,N,&NA" in one column. In another column off to the right I am
counting those inputs. A total is then calculating those Y(which formulate
to be 100%) and N (which formulate to be 0%) and then averaging them.

However, I don't want the NA to be part of the average. Meaning, if NA is
input, then the count would be NA, instead of 0% (like the N). It throws off
the average and I want it excluded from the avg calculation

Any thoughts on how to get this to work??
