Has anyone figured out how to use Countifs to define 2 ranges and criteria, then have the result be a number of distinct names (3rd column)
I have read many of the posts, but I don't see anything that shows how to do this.
Assume I have 2000 lines of data, I need to know the total number of distinct colleagues for the CTC within the month specified.
CTC - 301-Renton
Month - Jan
#Distinct Colleagues = ?
