A.D.-

Take a look at "Supplier IDs" in the Products table in Northwind. It is MVF,
and you'll find a property "Allow Multiple Values" on the Lookup tab in Table
Design. If you open the Product Details form, you'll see that the combo box
exhibits the special characteristics needed to support the MVF. But if you look
at the form in Design view and select the combo box, that property is nowhere to
be found. It's ONLY when a combo is bound to an MVF that it takes on the
special characteristics. I don't think there's any way to make this happen for
an unbound control.

Walter,

I have not had any experience with multi-valued fields (MVF).

Considering your keen-ness and the situation explained by you, preliminary
study with Access 2010 seems to indicate that there could be an interesting way
to implement the functionality of MVF on simulated continuous form made up of
unbound controls.

It might perhaps become feasible for you to have the best of both worlds, in
a seamless manner, complete with MVF style drop down list having check boxes.

After some pertinent tests, I would try to post further details.

Best wishes,
A.D. Tejpal

John;
The only way I can think of is to open a bound single record form from the
add/delete/( add an edit button) using the record IDs .
Kind of a kludge to use another kludge.
