Calculating between two different dates/time

[sheilakhull]

This is probably pretty simple but I can't see it right now. I have an entrance date/time in cell F19 & an exit date/time in cell G19. I need the number of hours between the two.

Any help is greatly appreciated!

=Exit Time-Entrance Time

and format the cell that houses the formula as [h]:mm
