How can i prepopulate the rigth bucket of a list collector once a variable has changed

[EricG]

I've read many of the posts on how to remove selections from the right bucket of a list collector when a variables changes and can get it to work.

what i can't seem to get is how to populate the right bucket when a variable changes.

this is compounded further should the variable change again prior to submitting the form.

What i have is a list of Positions.  Next there is a Matrix table of Apps to Position.

On my form i have a Position Select box, this update the Reference Qual of the List collector to show only those apps to need for the position.  My users would like that "List" to automatically populate the right side of the list collector.

e.g. User selects Value 1  - List collector filters on this value and populates the right bucket automatically

Now user selects Value 2 -  list collector clears right bucket, requeires, then auto populates right with new values.

I'm not sure that this is the best action and would be open for another idea on how to show required programs for a given position

OK, I'm half way there

I have the script include and the Client script working to 

1. Populate Left Side with New Values based on Variable 1

2. Right Side clears old values and updates Left side if Variable 1 changes.

Is there a way to automatically move the Left side values to Right side?

or maybe just make rigth not visible.
