COMPARE DATES and RETURN Yes or No

Good Day Community,

Need for field Timely to result in "Y" or "N".  Using a Label to display Timely.

If Closed <= Due, Timely = Y and 

If Today > Due Date, Timely = N or

If DaysOverdue <1, Timely = N

       End              Due         Closed       Timely     Days Overdue

If(ThisItem.Closed <= ThisItem.Due, "Y" && Value(DaysOverdue.Text) < 1, "N", Blank())

There isn't an error on the syntax, but not getting the result of "Y" or "N"

When the below was tried, all the rows returned "Y". None were "N"

If(ThisItem.ClosedOut <= ThisItem.Due, "Y", "N")

Any assistance would be greatly appreciated.
