MySQL Query in PHP error - php

Question

I have a problem with an query that won't work.
The one that needs to set the rank to 2 works, but the one that needs to set vip to 1 doesn't work.
I just get an white page.
What is the problem?
<?php
session_start();
include ("includes/config.php");
$lid = $_SESSION['lid'];
$uQuery = mysql_query("SELECT * FROM users WHERE id = '".$lid."'");
while($uFetch = mysql_fetch_array($uQuery)){
$uuser = $uFetch['username'];
$umotto = $uFetch['motto'];
$ucredits = $uFetch['credits'];
$upixels = $uFetch['activity_points'];
$ubelcr = $uFetch['belcredits'];
$urank = $uFetch['rank'];
$ufigure = $uFetch['look'];
}
if($urank < '2'){
mysql_query("UPDATE users SET rank = 2 WHERE id = '".$lid."'");
mysql_query("UPDATE users SET vip = 1 WHERE id = '".$lid."'");
}
Header("vip.php?succes=1");
?>

Answer 1

mysql_query("UPDATE users SET rank = 2,vip = '1' WHERE id = '".$lid."'");

Answer 2

Not exactly what you're looking for, but looking at the queries you could simplify to:
session_start();
include ("includes/config.php");
if(isset($_SESSION['lid'])){
$lid = $_SESSION['lid'];
$query = "UPDATE users SET rank = 2, vip = '1' WHERE rank < 2 AND id = ".intval($lid);
$result = mysql_query($query) or die(mysql_error());
header('Location: vip.php?succes=1');
exit;
}
