Can anyone see something obvious that is causing this formula to throw an "unparseable" error?
=IF(AND(Status4 = "Not Started", [Workdays since Start Date]4 < 0), "Green", IF(AND(Status4 = "Not Started", [Workdays since Start Date]4 > 0), "Red", IF((AND)Status4 = "In Progress", [Workdays since Start Date]4 < 0), "Green", IF(AND(Status4 = "In Progress", [Workdays since Start Date]4 > 0, [% Complete]4 < [% of Duration Passed]4), "Yellow", IF(AND(Status4 = "In Progress", [Workdays since Start Date]4 > 0, [% Complete]4 >= [% of Duration Passed]4), "Green", "Red"))))
