I have a hard to word question in my mind. I want to generate a report that counts the unique value of a list of people that only appears once throughout that search.
So, for instance if I want to search from 1/12/2016 ... 1/1/2017 for a group of classes and the list of people show up as:
Only Mark will show up as unique student so it will be 1 for that search period. Subsummaries can work as well for me, I am not picky. I just cant seem to think of the right question/solution to achieving that.
