> The itemset for a select control is an instance that other
> controls in the form insert into.  A trigger allows the user
> to delete from the list -- click one or more in the select
> control and click the "Remove" button/trigger.
>
> All is working except that the reference to the select
> is not recalculated  -- it lists all the strings that
> were ever selected.

> I am not sure if there was another step or this is a bug.

> I can point you to a the form, or, complete what I started below
