[AS 2.0 MX PRO 2004] Does loadvars work from a .swf that loaded into a preloader

I have Beginning.swf that loads main.swf. Within main.swf I am using loadvars to send data to a .php file. Thus far, I am using

import mx.controls.Alert;

LV.sendAndLoad(“http://www.url.com/file.php”, loadvarsVariable, “POST”);
loadvarsVariable.onLoad = function(){
Alert.show(data, “test”);

to see if it will load, and the alert box doesn’t appear :jail:, So I want to conclude that the call to the .php file isn’t going through. Because main.swf is embedded within Beginning.swf, the call won’t work. I know that the code works because when I test main.swf by itself, the Alert box appears. I have also ensured that there is an Alert object within the Beginning.swf library. This allows alert boxes from main.swf to appear in Beginning.swf. Does anybody have experience dealing with this? Does anybody know if newer versions of Flash/Actionscript behave any differently than this? Is there a work around for this problem, any Open Source solutions?:disco:
