I have a Google Sheet I'm using to geocode addresses, which shows where current road closures are located.  In my table, I have a date field StartDate and a number field Duration.  Duration equals the number of days the road will remain closed after the StartDate. I need a way to automatically delete the row when the duration of the closure has elapsed (i.e., StartDate plus Duration = new date when row will be automatically deleted).  Is there an easy way to accomplish this delete? I am not a programmer, so any help would be charitable.
