Im a little rusty on framesets, but I seem to recall the answer to this one.
First point, use the URL of the page that should appear in the lower right frame.
Second, use the target="frame" attribute to say which frame it appears in.
Hang on, Il try and dig out the actual <href> tag your using. Ick, autogenerated code.
<a href="http://www.geocities.com/castledaystar/bg2cd.html"> should be
something like:
<a href="http://www.geocities.com/castledaystar/bg2cd.html" target="main">
