Listbox problem on form

[muriel]

I created a few listbox tables linked to a main table with the lookup wizard. I have a main data entry form created from the main table, which contains the listbox tables.

The problem - the form will not allow the user to move on to the next record until every listbox field is filled out (a selection is made from the listbox). Is there any way to avoid forcing the user to select from every listbox on the form and leave some fields with listboxes blank?

Thanks much!!
