The problem appears to be a little complex. You should host the site all on one domain and then things should work much more simply as I am getting errors about permission denied which often happens with frames and iframes accross domains. The iframe appears to be on geocities while other content is on www.kappazetapsi.com. Add to this the fact that:
does not appear to exist, things get messy.
You might be able to use a workaround though. Try setting the url field in the custom.js to something like:
and just leave the target field empty. But, whatever page you use as the src, it must exist.
