How to add multiple values to a field?

How to add multiple values to a field?

Hi,

I am trying to make a field & form rule to change the subject of a change. But it fails.

I want to change the title to be

Title + Value1 + Value2.


Example.

Title==TEST
Value1==10.0.0.0
Value2==New York


When the change is submitted i want the title to be changed from "TEST" to "TEST - New York - 10.0.0.0"


How can i accomplish this? I have tried :

var SITENAME=$CS.getValue("UDF_CHAR3");
var LAN=$CS.getValue("UDF_CHAR1");
var CHANGETITLE=$CS.getValue("TITLE");

$CS.setValue("TITLE",[CHANGETITLE] - [SITENAME] - [LAN])
