Perhaps try this instead:

Add to config.php:

//comment page default
$CommentPage = 'Comments-{$FullName}';

//check for CommentPage PTV
$compage = PageTextVar($pagename, 'CommentPage');

// no PTV? Set to default
if(!$compage) $compage = $CommentPage;

//define page var {$CommentPage}
$FmtPV['$CommentPage'] = "'$compage'";



Then you can set on any page an alternative with a PTV
(:CommentPage: AltCommentPage:)

and use PV {$CommentPage} in all links and form target definitions
etc.
