how to determine active radio button

[Electrocutioner]

Sub rbtTest_CheckedChange(Checked As Boolean)
   Dim rbt As RadioButton
   
   rbt = Sender
   RadioButtonIndex = rbt.Tag
   UpdateCheckBoxes
End Sub

what form is "rbt" in that I can determine which button was selected.
I wish to branch program code from here to handle the button selected.

Thanks for your help!

If I understand correcty, all you have to do is use the radioButtonIndex in a select clause:

if checked then
  select radioButtonIndex
     case 0
       'do something for this
     case 1
       'and for this
   end select
end if
