ActionScript error when attempting call method within PHP file - php

Question

I have been following a flash tutorial online and I have created a simple flash interface. I am trying to retrieve data from my SQL database via a PHP file and display. I get the following error when I compile:
Error #1009: Cannot access a property or method of a null object reference
var variables1:URLVariables = new URLVariables();
var varSend1:URLRequest = new URLRequest("databaseCall.php");
varSend1.method = URLRequestMethod.POST;
varSend1.data = variables1;
var varLoader1:URLLoader=new URLLoader();
varLoader1.dataFormat = URLLoaderDataFormat.VARIABLES;
varLoader1.addEventListener(Event.COMPLETE,completeHandler1);
variables1.comType = "requestEntries";
varLoader1.load(varSend1);
function completeHandler1(event:Event):void{
if(event.target.data.returnBody ==""){
gbOutput_txt.text = "No data coming through";
} else{
gbOutput_txt.condenseWhite = true;
gbOutput_txt.htmlText = "" +event.target.data.returnBody;
}
}
My code exactly matches the code that is used within the tutorial. I have modified the php file to simply return "" so the issue almost definitely lies within the action script...I think :S The compiler falls over when he completeHandler1 function is called. What do you think could be causing this?
Thanks in advance.

You need to declare the completeHandler1 function before you attempt to use it anywhere else.
Here is your code modified to describe what I am talking about.
var variables1:URLVariables = new URLVariables();
var varSend1:URLRequest = new URLRequest("databaseCall.php");
varSend1.method = URLRequestMethod.POST;
varSend1.data = variables1;
function completeHandler1(event:Event):void{
if(event.target.data.returnBody ==""){
gbOutput_txt.text = "No data coming through";
} else{
gbOutput_txt.condenseWhite = true;
gbOutput_txt.htmlText = "" +event.target.data.returnBody;
}
}
var varLoader1:URLLoader=new URLLoader();
varLoader1.dataFormat = URLLoaderDataFormat.VARIABLES;
varLoader1.addEventListener(Event.COMPLETE,completeHandler1);
variables1.comType = "requestEntries";
varLoader1.load(varSend1);
Give this a try and let me know if it works.
