The above "else;" will cause you some grief and is certaily an error. The
shouldn't be a semicolon after else there.
May not be the only mistake either, but I haven't looked much further.
I also think that "if ( !$comments )" should be;
if(!empty($comments)) but it's past my bed time and I haven't given ie much
thought.
