error when executing procedure from PHP

[sdfv sdfv]

Hi,

I created a stored procedure in Mysql 5.0 (test()). It works.
Now i tried to execute it with PHP (5.0), but i get the error:
"Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in c:\storedprocMy.php on line 5"

Thanks for helping

The code:
<?php
$link = mysql_connect("localhost", "root", "xxx")
or die("Impossible de se connecter : " . mysql_error());
$dbsel = mysql_select_db('reserv', $link);
$result = mysql_query($link,"call test()");
while ($row = mysql_fetch_assoc($result)) {
$nom = $row['logon'];
$resnr = $row['resnr'];
echo $nom;
echo $resnr;
echo "<br>";
}
mysql_close($link);
?>
