Suppose you have the 5000 names in Sheet2 Name in ColA and Yes/No in ColB

In sheet1 you have the 5 names in A1:A5. In B1 enter the below formula and
copy that down to A5

A1 = name1
In B1
=SUMPRODUCT(--(Sheet2!$A$1:$A$5000=A1),--(Sheet2!$B$1:$B$5000="Yes"))

If this post helps click Yes

Hi, I have sheet with a list of 5 names in and another sheet with the same
names (about 5000) in total and yes or no recorded against each of these
names.

How do I count from the how many times yes is against a particular name?

Thanks
