To the extent that it might be possible with any of them (and I doubt it's possible with formfields), vba coding would be required and the code for each would be quite different. It's not something I'd be inclined to undertake unless (a) there is a pressing need to not have both the selection and the corresponding value show (with formfields, this can all be done via field coding without resorting to vba); and (b) a specific application requiring it was being considered.
