Help finding correct DAX.

[08Tedz40]

I need some help fining the correct Dax to so that this ADA doesn't break when it combimes the Multi years. they seem to work at the month level and year but once you start selecting multi years the dax breaks and gives weird data. 

the months is the program months measure.  the AMA is just getting a SUM of all years the and the ADA(Year) is for some reason just taking whatever the last year is.

I was able to fix it with these 2 functions.

Average Attendance (AMA) = CALCULATE(IF([Program Months]>[Progarm Months Ran],[Average Yearly Attendace (AYA)]/[Progarm Months Ran],[Average Yearly Attendace (AYA)]/[Program Months]))

Average Yearly Attendace (AYA) = CALCULATE(SUM([ADA])/[Program Year])
