Help with Php MySqL Flash tutorial

Hello, i’m new here and i have a problem right at the beginning.
I just can’t get this little script from this tutorial to work:
http://www.kirupa.com/developer/actionscript/flashphpxml_integration.htm
I created the database on my server, executed the query properly, the connection seems to be fine, but i have no data on the flash movie, if i hit directly sites.php on the browser i get this warning:

Warning: mysql_numrows(): supplied argument is not a valid MySQL result resource in /mylink/sites.php on line 10
**Database Output

[LEFT]here’s a bit of the code:

$user="****";
$password="****";
$database="fitflash";
mysql_connect("sql.****.com","****","****");
@mysql_select_db("****") or die( "Unable to select database");
$query="SELECT * FROM contacts";
$result=mysql_query($query);

$num=mysql_numrows($result); // the warning

mysql_close();

Please help i really need this to work…
