>Yep, I did that already. I even did ThisForm.OptionGroup1.Option2=1 and then ThisForm.OptionGroup.Option2.Click() and then even SetFocus(), still same problem. I have to physically click on that 2nd radio button to get the first radio button to turn off.

You missed Sergey's point. Don't touch the Values of the individual option buttons, only the Value of the group.
