NotInList Event

[RB]

I have a combo box whose source is a table
called "Ownership". I want this combo box to update if a
user enters a customer name not in the list so that
anything unique is added to the list for future use. I
have everything set up, and now I'm not sure where to go
with the code. I can't find any help on this anywhere or
an example of how to use this event. My combo box is set
to LimitToList=Yes and I need to know the code for the
event procedure for the OnNotInList Property. Thanks for
any help.
