I think this would work both places:

   $backname = preg_replace("/-Topic-.*\$/", '', $name);

in other words

   $name = PageVar($pagename, '$Name');
   $backname = preg_replace("/-Topic-.*\$/", '', $name);
   $FmtPV['$BackName'] = "'$backname'";

or maybe

   $name = PageVar($pagename, '$Name');
   if (preg_match("/-Topic-.*\$/", $name)) {
     $backname = preg_replace("/-Topic-.*\$/", '', $name);
     $FmtPV['$BackName'] = "'$backname'";
   }

makes {$BackName} always return the page's name up to the first "-" in
"-Topic-".
