To use the ActiveX option buttons, you will need to group them by Question. To do that for a given Question:
• Select one of the buttons and click the Properties button. In the list of properties, assign a value to the GroupName property.
• Use the dropdown at the top of the Properties list to select another button that should belong to the same group. Put in the same value for GroupName that you used in the first button. Repeat this for all the buttons in the first group.
