I'm wrestling with resuming a paused script.

Background:

• 
  Script 1 checks user-input fields for blank entries; if found, calls script 2
  Script 2 opens a window with an explanation of the problem, a field in which to enter text for input into the blank field, and a "Cancel" button [script 3: Close window, halt script] and a "Correct" button [script 3: Close window, return text to appropriate field]. Both buttons resume Script 2.
  

Problem: I would like to have the ability to resume script 2 not only from the Cancel or Correct buttons, but also by a script trigger (on object Save) from the field; this would allow the user to avoid reaching for the mouse after having keyed in the correction.

I have looked over the forums, and it seems that others have run up against this and get the impression that there is no resume step that can be invoked from a script trigger in the same way it is from the button.

My question: I could fix this if there is a scripted way to invoke a button click, by having a script trigger which invokes a script to <>. Is there a way to do this, perhaps for example by using the button's "Object Name"?

What fires Script1...a button?

This is an old demo that shows how to handle pauses, cancels, etc. Taking it apart may help.

That's correct, a button.
