Count # of rows in a table that have data but exclude double counts

[John MCarthy]

Hi,
I am working with a table of data in excel. Under each column I want to count the number of rows to the left of the column that have at least one cell with a number >0 (greater than 0) in the row. However, I want the formula to review a column of data labels to the left of the data range and if the same label appears more than once in the column to only count one row for that data label.
E.g. if the table has 5 rows with data in it but one of the rows has the same data label the result should only be 4.
I think its some kind of a variation of the SUMPRODUCT formula and can't figure out how to exclude the double count of rows that have the same data label, any suggestions on a formula for this?
Many thanks,
John
