>I had subclassed the standard combobox into 4 unique subclassed comboboxes. Each of the 4 had been set up with the controlsource referencing a table instead of a view of the table. Each combobox was place in a column of a grid replacing the normal textbox. The controlsource of the each combobox in the grid referenced the view of the table instead of the table.
