True/False indicator based on a measure?

OK, let's see if this works.

I apologize for not including the school variable in my initial question. I didn't realize it mattered. 

Here's what you will see in the linked report. AbsRate is calculating properly in the top table, but the # and % of students chronically absent does not vary by school the way I want. School A has 2 students, 67% chronically absent. School B has 3 students, 100% chronically absent.

It does seem like % chronically absent is fine, it's just the count of students chronically absent that is messing up the %. It's dividing 5 (number of chronically absent students in the whole division) by 3 (number of students in a particular school)
