I was working on a way to track some task hours and minutes... came up with this:
One of the problems I ran into is that if you put "00" (double-ought) or any minute with a preceding zero, it would error. You can see the work-around I made, not the most elegant, I admit.. If Smartsheet could ignore preceding zeros, it would save a lot of IF statements (see [Start Time] and [End Time] columns)
