I already have a formula created that automates the RYG ball based on due dates...
=IF(Complete1 = 1, "Gray", IF([Due Date]1 < TODAY(+3), "Red", IF(AND([Due Date]1 >= TODAY(+3), [Due Date]1 < TODAY(+7)), "Yellow", IF([Due Date]1 >= TODAY(+7), "Green", "Nope"))))
What im having an issue with is whenever the cell in the due date column is blank, the RYG ball automates to red. I would like to automate it to Gray whenever the cell block is empty but everytime i plug the IF(ISBLANK([Due Date]1), "Gray" it doesn't do what i need it to. If i put it in the beginning it doesn't allow me to have a date before today (Like if I need to back date something), at the end it does nothing and anywhere else makes it "unparsable" or "invalid".
here is a screenshot of the sheet
