>>I have a combo with 2 columns. One of the column widths is set to zero, but it still appears as a narrow column. Any ideas how make it invisible? Columnwidths=100,0

>If you want to display only one column you can set the ColumnCount property to 1, even if the BoundColumn property set to 2.

You hit the nail on the head, it worked.

>I often do this when the second column is a primary key of the combo's row source and the ControlSource is a foreign key.

The is exactly what I am trying to todo. I have just created a class called cboFK. Problem solved forever. Ain't fox great!

P.S. Thanks Lorne and Ken for your troubleshooting help.
