ActionScript 2.0 :: Get Event RSS Showing On Band's Website?

My band has a reverbnation profile, and I just recently started editing a flash7 site template that I purchased for the band. I happen to know enough to edit everything that is existing, but adding new content is a bit beyond my imagination and most of the tutorials I have found are all for creating new movies and use AS3 instead of AS2.

I created a new "dynamic" "classic text" text field (instance name of "rss" - variable set to "rss_output") in layer 1 of a section of my scene (movie clip) called "pages_tours".There is no other item in layer 1, frame 1 of this movie clip.In this thread: the author states that he was able to call xml data from another domain and post it on his site and this could possibly be used to snatch & display RSS data as well.I had created the proxy.php file, with code inside, saved as proxy.php (no .txt attached.)

PHP Code:

<?php $url = $_POST['http://www.reverbnation.com/rss/artist_shows_rss/**mybandnamehere**'];readfile($url);?>

I right clicked the frame of layer 1 and clicked "actions" and then pasted the code presented in that thread.

Code:
var Sender = new LoadVars();
var GetData = new XML();
GetData.ignoreWhite = true;
GetData.onLoad = function(success) {

[code]....

I tried a CTRL+ENTER test run and nothing happened in the page_tours area of the site.There were no compiler errors.
