Avoid from the error message: "FRM-41816: Attempt to create existing timer"

Question

Hi,
I create a timer in "on-insert" trigger in data-block level, like this:
timer_id := Create_Timer ('saving_inserting_timer' , 1 , NO_REPEAT);
in the trigger "when-timer-expired" in form level,  I use this timer, like this: 
timer_id := FIND_TIMER('saving_inserting_timer');
I know  that I should write:
DELETE_TIMER('saving_inserting_timer');
to avoid the error message frm-41816, and I tried to  write this line in a several places in the code (in both triggers).  But I still get this error message.
Thanks in advanced,
Elad

Hi Elad,
in ON-INSERT trigger write
timer_id := FIND_TIMER('saving_inserting_timer');
IF NOT Id_Null(timer_id) THEN
  Delete_Timer(timer_id);
END IF;
timer_id := timer_id := Create_Timer ('saving_inserting_timer' , 1 , NO_REPEAT);
in WHEN-TIMER-EXPIRED trigger wrote the below code
IF NOT Id_Null(timer_id) THEN
  Delete_Timer(timer_id);
END IF;
No two timers can share the same name in the same form instance, regardless of case.
Hope this will help
