>I have a combo box that I have created on a form. My data environment consists of two tables which are presently contain no records. Using the builder, I can get the combo box to work as long as I do not tell it where I want the combo selection to be stored. When I do, the previously working combo box shows blank at run-time. Weird!....any ideas?

When you say blank do you mean that combo doesn't display an initial value or that there are no items to choose from the drop down list. Can you post your rowsource, rowsource type and control source here?
