Как вывести тег {news_num} {user_num} {comments-num}?

$tpl->load_template ( 'main.tpl' );

$row = $db->super_query( "SELECT COUNT(*) as count FROM " . PREFIX . "_post" );
$stats_news = $row['count'];

$row = $db->super_query( "SELECT COUNT(*) as count FROM " . USERPREFIX . "_users" );
$stats_users = $row['count'];

$row = $db->super_query( "SELECT COUNT(*) as count FROM " . PREFIX . "_comments" );
$count_comments = $row['count'];

$tpl->set( '{news_num}', $stats_news );
$tpl->set( '{user_num}', $stats_users );
$tpl->set( '{comm_num}', $count_comments );
