[Quoted] Timers don't work in this way. A Timer runs in the background and when it expires causes some specified action to occur via the When-Timer-Expired trigger. The Timer only starts after control returns back to the screen, ie. the trigger that contains the Create_Timer has terminated, plus any associated triggers.

Re-locate exit_form to the When-Timer-Expired trigger. Received on Fri Nov 03 2000 - 03:56:15 CET
