Thanks Shane! I can't believe I used the text delim in one place but not
where you showed me. Makes total sense now! I think if you don't call update
and then try to reference the Link in another script before saving you get
an error. I could be wrong but for some reason in one of my VB scripts I had
to do it so I've just been doing it ever since. Thanks also for the speed
tip. I've got my O'Reilly book next to me but they didn't really delve into
what's the best way to do things. Man, I've been able to pick up most any
language because they all follow similar concepts but AS has been one of the
toughest just because its so simple!

Thanks again Shane!
