PHP und mysql prob.

[Rene Enskat]

Also ich habe folgendes script:

<?
        session_start();

        $link= mysql_connect( "localhost", "", "");
        if (! $link )
                die("Couldn't connect to DB".mysql_error());
        mysql_select_db ("aktien")
                or die ("Could not select DB $db".mysql_error());
        $sql="select * from menu_name where lang=$lang and menuid=$id";
        $res=mysql_query($sql);
        $a_row=mysql_fetch_array($res);
                print "<H1>$a_row[besch]</H1><BR><BR>";

        $sql="select * from menu where user='$grp' and menuid=$id and
lang=$lang order by menuorder";
        $res=mysql_query($sql);
        print "<ul>\n";
        while ( $a_row=mysql_fetch_array($res) ) {
                print "<li><A href='$a_row[link]'>$a_row[besch]</A></li>";
                }
        mysql_close($link);
        print "<br><br>\n";
        print "<A href=/menu.php?id=0>Zurück zum Hauptmenü</a>\n";
?>

und im browser bringt er folgenden Fehler:

Warning: Supplied argument is not a valid MySQL result resource in
/u/apache-ssl/htdocs/menu.php on line 11




     Warning: Supplied argument is not a valid MySQL result resource in
