>I need to provide an easy way for users to blank out a numerical field that contains previous input. VFP won't allow one to just delete the field's value, which I don't understand why. When I attempt to delete the value from the field, the field automatially resets itself to zero. I don't want to use null values for practical reasons.

Well, even when the field is blank it is equal to 0. Does it really matter whats shown? Anyways, you can get rid of the 0 by doing a BLANK on the field. I think the only time its truly relevent, however, is if you have logic that uses IsBlank() on the field.
