I have been using this function to count the number of unique text values in a data set:
=SUM(IF(FREQUENCY(MATCH(B2:B10,B2:B10,0),MATCH(B2:B10,B2:B10,0))>0,1))

It works great if I want to count number of unique text values overall. However, I want to count the occurences of unique text values if they meet specific criteria. (Like a countifs function would if it could count unique text).

Any ideas?
