            $row = mysql_fetch_assoc($retid);

$userpw = $_COOKIE['forum_userpassword'];
            $retid_pw = mysql_query("SELECT * FROM users WHERE password = '{$userpw}'");
            $row_pw = mysql_fetch_assoc($retid_pw);

$sql = "SELECT
                userid, password
            FROM
                users
            WHERE
                userid=$userid";

$result = mysql_query($sql);
        $row_pw = mysql_fetch_array($result, MYSQL_ASSOC);
            if($row_pw['password'] == $userpw) {
                print_r ($row['username']);
                echo "<br />\n<a href="login.php">User Panel</a><br />\n";

} else {
                echo "Gast (<a href="login.php">Login</a>)<br />\n";
                echo "<a href="login.php">Registrieren</a><br />\n";
                echo "<a href="login.php">Info</a><br />\n";
