Can a combo box - Link to a Table

[Blair Greene]

Can anyone tell me if it's possible to link
a specific "combo box" to a specific table ?
i'm trying to avoid duplicate bar codes from
being entered into a combo box, and tables
have the feature "yes-no duplicates" however
I dont see that feature on form combo boxes..

This is the third question that you posted on this topic yesterday. Are you aware that yesterday was Thanksgiving and that today is also a holiday for most people? In each of the posts you phrased the question slightly differently. I still cannot figure out what you are asking! Would setting the limit to list property of the combo to yes be the correct answer to this question?
