I am trying to use the RAGB indicators to look at if a Due date is set and then setting the Indicator to Red if in the past, Yellow if in the next 3 days and Green if in the future beyond 3 days. We are also using the Blue to indicate if the task is complete. This works fine with the following formula, however for blank Due Dates it shows Yellow
=IF([Task Completed]1 = "Yes", "Blue", IF(TODAY() - [Due Date]1 > 0, "Red", IF([Due Date]1 - TODAY() < 3, "Yellow", "Green")))
What I would like to also do is look to see if the Due Date is not Set and Return a Value of Not Set if the cell is blank and keep the above indicators when they meet the criteria.
Can anyone advise as how to do this?
