Problems satrting out in php/Flash

I have been working professionally in php for some time and thought I should learn how to render data in flash from my scripts. My first exercise from kirupa.com has been very confusing to say the list. This is the heart of the tutorial i.e. using loadVariables to get the contents of a script on my webserver. This actionscript is attached to the textbox which I have called myVar

onClipEvent (load) {
//assuming you have a personal web server and PHP installed locally
loadVariables(“http://localhost/testflash/index.php”, this, “GET”);
}

Whereas the following is the php script that the above action script is meant to be writing to the swf.

However though I can tell that my script is connected with I still get a blank page for all my efforts.

Please I would appreciate help from someone pointing out where I am screwing up. Thanks in advance.
