It is possible to loop through the ItemsSelected collection of the list box
to generate a delimited string of the values, and then assign that to a
bound field, but there is no benefit in storing the data that way.
Wherever you have many values related to one record, you *really* need to
create a related table with a one-to-many relationship to the original one.
The simplest interface is then a subform where the user can select multiple
values.
If you prefer, you can use program code to write the records in the related
table from the multi-select list box, but you would need to have a good
reason for going to that trouble, appending and deleting the related
records, setting the selected items in the Current event of the form, and
resetting them in the form's Undo event.
