Some scrip difficulties

I am trying to form a scrip that will (on ticket creation) add a watcher
to a ticket and then notify the original requestor and the newly added
watcher with an “AutoReply”.

I have tried to string multiple “On Creates” together but it seems that
the scrip with the “User Defined” action (the one that adds the watcher)
always gets executed after the notification scrips so the newly added
watcher does not get a notification. Is there a way to add a "Notify"
or “Autoreply” action inside of a “User Defined” action? Or is there a
way to force the scrip with the “User Defined” action to be executed first?

Thank You
