Help With As3

Hi there I have trawled the net for days trying to get this seemingly simple interaction to fuse.

I am working in flex but have built some classes and as3 files to handle some of the data.

What i have managed to do is: load some external xml data. this is held in a class file called [SIZE=3][COLOR=Blue]xml_data_loader.as [/COLOR][/SIZE]
This file hold about 20 vars that in turn contain the dynamic xml data.
What I cant do is retrieve this data in another function. in a file called: [SIZE=3][COLOR=Blue]external.as

[/COLOR][/SIZE]If I make the vars public it errors me and wont compile correctly.
would any guru be able to have a quick look??
