Hi everyone,

I want to count how many times yes has occurred once for each person. For example, Tony has 3 yes's, Frank has 2, Kate none.

I want another cell to count them and return a value of 2, one for all of Tony's yes's, and one for all of Frank's.

This is just a basic mock up, the real deal will have hundreds of names. Any suggestions?

Thanks for the feedback, i'd probably agree with you but i need to look into the frequency formula as i see it used for a few complex formulas, but i dont grasp how it works yet, ,maybe ill review it on the train later on

@dispelthemyth

Frequency for unique count is faster than Hager's SUM/COUNTIF idiom. Also, I believe a global distinct count is asked for...
