Question : Need help with global variables in AS 3

I'm new to Flash and ActionScript. I'm using Flash CS4 with ActionScript 3. I am trying to develop a program that pulls data from an XML file. One of the pieces of information that gets pulled is a text file name where disclosure information is kept. The reading of the XML file is done in an actions layer in frame 1 of my flash file.

Frame 2 of my flash file is where the disclosure screen is displayed. On the actions layer in frame 2, I want to read in the information from the text file retrieved in frame 1 and display it on the screen. The problem I'm having is with the idea of a global variable. I did some searching and a solution was to create an ActionScript Class and store my variables there. Then to access the variables, I would import the class and access the variable from the class.

When I do a trace on the global variable in Frame 1 it contains the data I want. However, when I do the trace in Frame 2, the global variable is null. I do not receive any compile errors or runtime errors. Can someone please help me figure out what I am doing wrong? If there is a different approach I should be using rather than the one I've chosen I am open to suggestions.

var AAPxml:XML;							// AAP Project Information
var AbstractList:XMLList;				// List of Abstracts from AAP Project Information

//load the XML
loader.addEventListener(Event.COMPLETE, onceLoaded);
 
function onceLoaded(event:Event):void
{
	AAPxml = new XML(event.target.data);
	AAPxml.ignoreWhitespace = true;						//don't consider whitespace as nodes
	banner = AAPxml.banner.image;						//get banner image file name

Answer : Need help with global variables in AS 3

Hi, I've tried replicating your structure according to your definitions.
are you sure you don't get any errors when compiling?

first of all, you should put your loader.load function in a try catch ....

secondly by commenting out some of the stuff that was throwing errors, i managed to get it to work where you variable is available in frame 2.

okay check the following.
you don't have a stop action in frame 1 so you're going to frame 2 immediately and trying to trace the variable before it's been defined in frame 1.
test that - stick a stop() action in frame 1 and a gotoAndStop() inside the onceLoaded after the xml is handled.
