You can use timer Error() event. It takes precedence over ON ERROR. TRY...ENDTRAY would be other alternative.

>It is coded in a timer. I don't make extensive use of timers and I have never tried to change the on error setting in a timer before. I guess this is disallowed? I did a quick search on that in the help, but didn't see anything. It was a quick search. Perhaps I overlooked it.
