Here are the errors that Firefox's Error Console keeps on giving me:

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]Warning: function makeRequest does not always return a value

Fixed the parse error now.

I don't know why it keeps on throwing up a

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]Error: uncaught exception: Permission denied to call method XMLHttpRequest.open[/quote]

when the file is not off-server...

Any ideas?
