Ical Applescripting - JStark sample code

I have added Ical event creation to my solution using some of Starks sample code and have added

some additional trial and error applescript. What I have come up with works great.

The one thing I lack is the ability to overwrite an existing event if I need to update information.

When I update in FMP and push the info I create duplicate events.

I have read a couple of threads on something similar but have yet to find a solution.

I have tried having FM create a "UID" but it doesn't seem to fly with Ical.

The one post I recall is Fenton Jones lending a hand. I just can't seem to grasp how I should obtain

and use Ical's UID data.

Can anyone simplify it for me.

It seems like it would make sense to generate or obtain the UID after the process of making/looking for "theCalendar"

and before the process of making "theEvent". I'm just not sure...

Thanks in advance!
