Please don't top post, and please send replies to the mailing list.
I'm cc'ing -novice. You have a much better chance at getting a
helpful response if you always send to the mailing list for questions.

I don't know much about triggers, as I haven't often needed to use
them. How do you know the trigger is not firing? People who
understand triggers and other such things may want to see a
simplified test case (including trigger code) that shows the behavior
you're seeing.

Good luck!
