I can't believe I'm having a problem with this...........

I have a ReasonCode table
idReason Int
cReason C(20)
cExplanation C(200)

I have a grid whose RecordSource("crsGrid") contains an idReason field.

I need a drop-down combobox which shows cReason value as both the displayvalue and the drop-down list, but puts the proper idReason into crsGrid.

What are the proper properties to set on the combo-box

TIA.............Rich
