as to your question, you do not need a frame  to make options
exclusive. What you can do is just select all the options on that page
(using Ctrl to add to the selection), then set the Group Name property to
some specific name. Do the same on all the pages  with the same name. That
will cause all the option buttons  to become a member of the same
GROUP...i.e., just like all being within the same frame, but less work.
