Thanks for the time there Bill:

It is very simple as follows
RowSourceType = 1 - Value
RowSource = Contract Carrier,Broker Company,Reship/LTL Carrier,
Dedicated Cartage,Shuttle,Air & Boat,Intermodal

so the combo has six diferent values, we need the user to type a new one and execute the form.
Next time we instantiate the form, it does not need to have whatever they typed last.
I believe is a Style attribute between combo and list box.
I need the user to type whatever s/he pleases and don't need to add programatically nor to stay for next run.

Will that help?. Thanks for the responses
