Changes made via combo box not saving?

[RSW]

I have a simple form that has a table as its data source; it's mostly text boxes, with one combo box.

For some reason, changes made using the combo box are not made in the record. A selection can be made using the drop-down, or an update can be typed into the combo box, but move off the record, close the form and re-open it, and the change is gone. Changes made in the text boxes work correctly, though.

Does anyone know what the problem may be? The combo box is enabled, and not locked.

Thanks in advance!

What is the control source property of the combo? I suspect it's blank.

The control source of the combo box is "Location", which corresponds to the column in the table. The row source is a simple select query from a lookup table.

It should save then. Can you post the db here?
