I have 2 columns, column A, which read either class 1 or class 2 througout. Column C with dates. Here's my problem, I use COUNTA to find out how many cells contain data in C. Out of the total quantity of cells in column C with data, how many are class 1 and class 2.
So, if the total of column C is 270, how many in column A are class 1 or class 2?

Any suggestions?
