Somehow I deleted the orginal thread but here it goes on...

I have a Combobox with the following:

ControlSource: auth.authtype
RowSource: authtype.authtype
RowSourceType: 6 - Fields

and it all works good, but if the user clicks the space bar, it goes ahead as a blank in the ComboBox. I tried BoundTo but doesn't work. How to prevent a space or any other data that is not of the authtype.authtype be in the Combobox?
