I'm calculating the workdays between two days and updating the status in a different column. How do I make the formula ignore blank cells in the Install Difference column?
=IF([Install Difference]@row >= 21, "Late Over 4 Weeks", IF([Install Difference]@row >= 11, "Late Over 2 Weeks", IF([Install Difference]@row >= 2, "Late", IF([Install Difference]@row >= 1, "On Time", IF([Install Difference]@row < 1, "Early")))))
