I apologize but I cannot seem to wrap my head around this.
My goal is to count the total values in a multi select column based on another columns criteria.
I figured I could combine the use of CountM and CountIFS but I have not been successful.
Here is an example.
The goal is for me to determine the total # of Reps Per Manager.
There are about a 400 unique Reps, this is just a cleaned up example.
