Hi,

I have a column B which can have input as 1, 0,a or sh. Another Column C can
have input as I,D,X,M. I want to count the number of "I"s in column C which
have "1" in column B. In other words if column B has o ans column c has I , I
do not want to count it.

Column B Column C
1 I
0 I
sh D

Thanks for your help.
