>I think I had a similar problem to this and found that I had forgotten to set the column's ControlSource property to something. The ComboBox had behavior similar to what you mentioned - the column containing the ComboBox would all contain the same value. That's at least one thing to check, if you haven't already.

The Column has different values. Since two countries can have the same country ID but be in different continents, the country ID show the country of the current continent. I decided to combine these two popups into one and do a REPLACE in the Valid event of the ComboBox. I would have been nice to have two ComboBoxes. Oh well...
