I have this formula which is working. However what it is not doing is picking up a Not started task sitting at 0% that it is overdue.
It only marks it as overdue once I move the task to an in- progress state.
=IF([Percent Complete]@row = 1, "Complete", IF([Percent Complete]@row = 0, "Not Started", IF(AND([Percent Complete]@row < 1, [End Date]@row <= TODAY()), "Overdue", IF([Percent Complete]@row > 0.01, "In Progress"))))
