Jim,

Option groups take a numeric controlsource which designates which button is selected.

THISFORM.OptionGroup1 = Alias.NumericField

Or you can leave the controlsource blank and in the refersh of the optiongroup you can;

DO CASE
   CASE alias.FirstName = "Jones"
      THISFORM.OptionGroup1.Value = 1
   CASE alias.FirstName = "Smith"
      THISFORM.OptionGroup1.Value = 2
   OTHERWISE
      THISFORM.OptionGroup1.Value = 1
ENDCASE
