Hello, it worked, but I had to modify the load_cities.php->

<?php
$bd = mysql_connect(“localhost”,”root”,””) or die(“Connection Error: ” . mysql_error());
mysql_select_db(“depselect”) or die(“Error conecting to db.”);

if(isset($_GET['id_country'])){

Hello, thank you for your help, but when I add a register this example works fine, the problem is when I need edit such register because the city associated with the register is not the right.

The problem is this line:

{name:'namecy',index:'namecy',editable: true,edittype:”select”,editoptions:{dataUrl:'load_cities.php?id_country=1'}}
