Making an option button default

I have a user form in which I am using a couple of option buttons. I am trying to make one of the the buttons as a default if none is selected. How can I go about doing it? Can anybody help me with the code?

Hello peedarp1985,

Say you have three option buttons named "OptionButton1", "OptionButton2", and "OptionButton3". When the User Form is displayed none will be selected. If you want "OptionButton1" to be set by default then...

Private Sub UserForm_Activate()

    OptionButton1.Value = True

End Sub
