I have two columns. A Time column and a Duration column.
I have a series of activities that last a set duration (5 min, 10 min, 15 min, etc.)
The first activity starts at 5:00 AM and lasts 5 mins. I would like the Time column for the next activity to be filled in as 5:00 AM + 5 mins = 5:05 AM and continue on until the end of the list.
How do I make this happen?
