I am trying to create a formula that returns the count of items past due, 0-30 days, 31-60 days, and greater than 61 days.
The formulas I'm using is (respectively):
=COUNTIF(AND([Past Due]2:[Past Due]18, "True", [# of Days Past Due]2:[# of Days Past Due]18, <31 >= 0))
=COUNTIF(AND([Past Due]2:[Past Due]18, "True", [# of Days Past Due]2:[# of Days Past Due]18, >=31 <= 60))
=COUNTIF(AND([Past Due]2:[Past Due]18, "True", [# of Days Past Due]2:[# of Days Past Due]18, >=61))
however, I keep getting the following error "INCORRECT ARGUMENT SET".
