Hi

I have a sheet which works out how many hours it takes to produce a part, but because its using multiplication and division, my sum is coming back as a number. i.e. 8.68 hours, if i put a start time in for a job say 07:00:00 and i want to add the 8.68 hours to it, how can i do this to return 15:40:00

Any hep would be great
