Multi-Select List Box question

[Guest]

I now have an Order form with a combo box on the 2nd page. This combo box
selects multible items and is set to continuous forms. I would rather have a
list box to do this. I created a subform for the list box and gave it all the
same properties as the combo box and set the property for Multi to Single. I
deleted the combo box from the form and dragged the list box over. I then set
the link Child/Master fields just like they were on the combo box. When I
make a selection(s), I get: "Index or Primary Key cannot contain a null
value". What am I doing wrong?
Thanks

A multiselect listbox does not return a value. You need to set the
Multiselect property to None.

I quess I will have to stay with the combo box for multible selection.

Combo boxes don't allow multiple selections.

I have the form set to continuous forms. When I enter an item there is
another combo box below it so that I can enter another item. These combo
boxes continue to drop down so that I can enter any number of items.
