Due to the amount of noise (aka spam) I have to approve first time posters
first. The list isn't down, I just didn't get through to approving your
message until this morning.

You want to use the "bindTo" parameter on the makeContainer() methods to
bind the 2 related select boxes together:
http://www.pengoworks.com/qforms/docs/extension_fields.htm#makeContainer
objForm.products_available.makeContainer("products_selected");
objForm.products_selected.makeContainer("products_available");
I would then use:
objForm.products_selected.setValue("existing,values,here");
To re-populate the list with the saved values. It should take care of moving
the values from one list to the next.
