MYSQL HJÆLP 2

jeg skal også bruge en MYSQL maillings liste, men den bruger også MYSQL og det kan jeg ik finde ud af, kan du lave en mysql database til denne maillings liste, den skriver således:

Warning: Supplied argument is not a valid MySQL result resource in d:\\home\\test\\www\\tester\\admin.php on line 58

og her er scritp:

<?
// ADMIN AREA
// HER ER DER MULIGHED FOR AT SENDE E-MAILS TIL HELE LISTEN


$sql_host = \"secret\";
$sql_user = \"secret\";
$sql_passwd = \"secret\";
$db = \"systems\";
mysql_connect($sql_host,$sql_user,$sql_passwd);
mysql_select_db($db);
if ($mode == \"send\") {
   
    if ($action == \"on\") {
    $res = mysql_query(\"SELECT * FROM mailliste\");
    $besked = nl2br($besked);
    while ($row = mysql_fetch_array($res)) {
   
    $modtager = $row[\"mail\"];
    mail($modtager,$emne,$besked);
       
    }
    ?>Mail sendt<?
    exit;
