What I am wanting to do is let a user choose from a combo box the data they
want and when they do so it will fill in another combo box for them. But
if they fill in the combo box with something that isn't in the combo box
list then I want to let them go and choose the data they preferr in the next
combo box that they would have had filled if they would have chosen something
that was in the first combo box.

My problem is that I wanting to use the (Control Source) = [Desc].(Column)(1)
expression which works until they type in something that isn't in the first
combo box. Then when they go to choose their on data in the second combo
box it won't let the user choose the data they want.

How can I bind a control twice or is it possible?

any suggestions?
