I have a spreadsheet with T8, T9 and T10 in a single column, Column C. I
have the sum to count each individually. I now need to be able, in column F,
to count the Y and N, split out by T8, T9 and T10 (column C). I've tried
counta and countif, putting in different parameters but it doesn't work.
I also in column H need to count the Y's again split out by T8, T9 and T10
and in column I (where I have dates) need to count them by T8, T9 and T10.
Help please
