I have my PHP file which outputs either <loginsuccess>yes</loginsuccess> or <loginsuccess>no</loginsuccess>.
http://redshiftltd.co.uk/dev/flexlogin/login.php

ThenI have my MXML to read from the file login.php either the <loginsuccess>yes</loginsuccess> or the <loginsuccess>no</loginsuccess>

If it returns 'yes' then the state changes to logged in. But the problem is that even if I switch the values over so that by default it presents <loginsuccess>yes</loginsuccess> to try and trick the response, I still get a login failed message.

Please advise!!

Code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">

<!-- Start of 2nd State, i.e when user has logged in -->
