Disable Option Buttons MS Excel 2010 VBA Code

How do I disable an option button or buttons (contained in a frame) based upon the selected option button (contained in another frame).  See sample of form attached.  If the No option is selected in the "Did you" frame, I want all the option buttons in the "If you" frame to be disabled.  Vice versa, If the Yes option is selected in the "Did you" frame, I want all the option buttons in the "If you" frame to be enabled.  I need this check done every time I press one of the buttons in the "Did you" frame.  Also, please be specific in what area of VBA you place this macro.  I'm guessing in the
Private Sub PWNoOptionButton_Click() section?

Thanks,

Bill J.
