Checkbox formula to check when date passed but that doesnt check if there is no date in cell
I have a simple formula to check the box when 28 days have passed the date in date column but when i drag this formula down to rows that dont have a date yet, it also checks them
this is my formula:
=IF(Date@row < TODAY(-28), 1, 0)
Im not sure what i have to do so the formula keeps it unchecked when there isnt a date. any suggestions would be greatly appreciated.
