Проблем с код за сортиране по desc и asc

elseif($_GET['video_order'] == "desc"){
				$getdata = mysql_query("SELECT *, (SELECT Count(videos.id) FROM videos WHERE videos.us_id=users.id) AS videos_count FROM users GROUP BY users.id ORDER BY videos_count DESC, users.id DESC LIMIT $cur, $max");
			} elseif($_GET['video_order'] == "asc"){
				$getdata = mysql_query("SELECT *, (SELECT Count(videos.id) FROM videos WHERE videos.us_id=users.id) AS videos_count FROM users GROUP BY users.id ORDER BY videos_count ASC, users.id DESC LIMIT $cur, $max");
			}

 index.php?p=members&favorites_order=<?php if($_GET['favorites_order'] != "desc"){ echo "desc"; } else { echo "asc"; } ?>

//ако няма зададен $_GET['video_order'], слагаме 'desc'
$sort = isset($_GET['video_order']) ? $_GET['video_order'] : 'desc';
//ако потребителят е хакер и в $_GET['video_order'] не е нито desc нито asc, трябва да се предпазиш и от това:
$sort = $sort == 'asc' || $sort == 'desc' ? $sort : 'desc';

$getdata = mysql_query("
SELECT *, (SELECT Count(videos.id)
         FROM videos
         WHERE videos.us_id=users.id) AS videos_count

FROM users
GROUP BY users.id
ORDER BY videos_count $sort,
       users.id DESC
LIMIT $cur, $max
") or die(mysql_error());

ORDER BY 
users.id DESC,
videos_count $sort
