Richard, Thank you for such a thorough response. I do not
have a many-to-many relationship between the meds table
and the patients. Only one med is assigned per patient.
The meds combo box simply selects a med from the meds
table and inserts it in the patient's med field. The code
I have now works well at intercepting a not-in-list entry
and adding it to the meds list. I simply wanted a way to
remove an item from the meds list in a similar way (see
http://www.mvps.org/access/forms/frm0015.htm).
Anyway, if this cannot be done I will try using your first
option with a check box for a new med and an option to
edit the meds list.
Many thanks
