$query = "SELECT id FROM adresser WHERE id > (".mysql_escape_string($_GET['id']).") ORDER BY id ASC LIMIT 1";
$query_handler = mysql_query($query);

if (mysql_num_rows($query_handler) == 1) {
	$nextid = mysql_result($query_handler, '0', 'id');
}
else {
	$query = "SELECT id FROM adresser ORDER BY id ASC LIMIT 1";
	$query_handler = mysql_query($query);
	if (mysql_num_rows($query_handler) == 1) {
        	$nextid = mysql_result($query_handler, '0', 'id');
	}

}

echo '<meta http-equiv="Refresh" content="5;url=index.php?id='.$nextid.'">';
