Please try this:
(count(if ISNULL([Days Past Due]) then 1 END)/(COUNT([Status])))
and let me know if the number returned is correct.
In your calculation, this calculation ISNULL([Days Past Due]) it returns back both the true and false values for every record. So that's why it is 100%.
Will This not Work?
1-(count([Days Past Due]))/(COUNT([Status]))
That did it! Thanks, Mavis!
No, that didn't work.
