Thank you for your rapid response, but that doesn't work. I'm trying to take a time, ex. 0700 (I don't want the colon in it --07:00) until another time, ex. 1513 (no colon), then present this in hours and tenths of minutes.

Eg A1 (0700), A2 (1513) is 8 hours 13 minutes, or 8.2 (b1) Everytime I put in 0700 as a number or a time, it either changes the number to 700, or puts a colon in it. And also, what happens if the time is from 0700 to 0100 (the following day), which is a total of 18 hours....

I'd appreciate any help!!!
