In general, option groups have at least two buttons. I'd suggest somthing like the following:

WITH ThisForm.PageFrame1.Page1.OptionGroup1
  DO CASE
    CASE .Value = 1
      * Do one thing
    CASE .Value = 2
      * Do something else
    OTHERWISE
      * Just an example
  ENDCASE
ENDWITH

The value of the OptionGroup with reflect which button is chosen.
