Combo Box: Key Column

There are two Columns in this Combo Box:

Column 1: MovieID

Column 2:Movie

 

Only one column will be seen in the Drop Down List. If the Key Column is not hidden then Users will see the MovieID, Column 1, and not the name of the Movie, Column 2.

 

By default, the Combo Wizard hides the Key Column, so Users will see the Movie name.

You May Have Noticed: This walk through the Combo Box Wizard accepted the default to Hide the Key Column. Why is this so? This Form saves the Primary Key, not the Text, to the Table so it goes with the Default. In a Normalized database there are only Key numbers, not Text, when you get to the final summary (tblMovieRented).
