I have a deluge script that works great when I'm adding a new form entry, but doesn't seem to fire when I'm editing a form entry.  The script hides a field based on the input value of another field on the form.  When I'm adding a new entry, the field is shown or hidden per the script.  When I'm editing an existing entry, the field is always shown no matter what value I put in the source field.  Is there something I'm missing?  Should the script work the same way on add and on edit?
