in my transport department i need to assign tickets to my drivers based on time of they enter to the office and when they go out for the service they have to delete automatically from the technicians list and when they come back they have to added at the end of the list of technicians.

I have about 100 technician at all but every they just about 50 of them will come to office and i want to check them with the time of entering.after they come back from the service the time of closing their last ticket will be the entering time of them to office.

so thanx
