I am trying to create a combobox for a description field (char 40) where the user can either select from a list of pre-defined entry (from another table) or enter the description directly in the field.

The problem is that if the user enter something in the combobox, instead of selecting a predefined entry, the value property of the combobox returns an empty value.

Any explanation ? There must be something I don't understand in the comboboxes...

Thanks for any help
