Well, it would be much easier if pages SubPage1 and SubPage2 were
bookmarkable and you would define your frameset just in HTML.
Is there any reason why you want to do that dynamically/ not with
bookmarkable pages? Also, you should put the different frames in
different page maps so that using one frame doesn't result in expiring
the other.
