Problem with my query...

[Jason Valdron]

Hi,
Can someone tell me whats wrong with my query?? (I use PHP)

$name = $_POST['T1'];
$location = $_POST['T2'];
$website = $_POST['T3'];
$msn = $_POST['T4'];
$aim = $_POST['T5'];
$icq = $_POST['T6'];

$username = $_SESSION['user_name'];
$query = "UPDATE users SET name = '$name', location = '$location', website = '$website', msn = '$msn', aim = '$aim', icq = '$icq' WHERE user = $username";
mysql_query($query) or die('Error, query failed');
