valid MYSQL result

Hej alla!
Något är inte som jag vill ha det

 <?php
$server   = "localhost"; // MySQL hostname
$username = "***"; // MySQL username
$password = "***"; // MySQL password
$dbname   = "***"; // MySQL db name

$db = mysql_connect($server, $username, $password) or die(mysql_error());
      mysql_select_db($dbname) or die(mysql_error());

$sql = "SELECT ip2nationCountries.country FROM ip2nationCountries,ip2nation WHERE ip2nation.ip < INET_ATON('".$_SERVER['REMOTE_ADDR']."') AND ip2nationCountries.code = ip2nation.country ORDER BY ip2nation.ip DESC LIMIT 0,1";

$countryName = mysql_result(mysql_query($sql), 0, 0);

// Output full country name
echo $countryName;
?>

Resultat:

Warning: mysql_result(): supplied argument is not a valid MySQL result resource in /export/vol1/unix/s/sneeze/public_html/test/test.php on line 40

Nån som vet vad jag har gjort för fel??
