Each option button you create must be associated with a particular group, identified by the group name. All of the option buttons in the group must be on the same page You can create new group names as needed or select an existing group name from the Group Name list. For each group you create, Rational® ClearQuest® creates a single label for the entire group. When you select an existing group name, the Group Label field displays the label associated with that group.
You can assign any value to an option button that makes sense for your schema. Values are displayed on this page as strings, but the way they are stored depends on the type of field associated with the option button. Although normally you should associate the same field with each option button in a group, you are not required to do so.
