One table has a field that can have multiple values. I don't know how to proceed to create an option group that show the value of this field.
When I add this field to the form, access automatically create a combo box that opens a small window containing many check boxes when you click it.
But I want the check boxes to be on the form and always viewable.
I created an option group and set correctly the ControlSource property to the name of the field, but the check boxes values don't change accordingly to the fields values. All the others fields are displayed correctly on the form.
Thank you.
