Help I need to subtract break time from the contracted duration worked. I am using a drop-down for contractors to select the time taken for a break. 10 min, 15, min etc… I have good scripts for breaking the duration of work into {HH}:{MM}. I just need a way to subtract the number entered above to work in a time context. Please advise. P.S. I am not using sheets. ---
