Flash CS5 AS3 Can not get Flashvars - actionscript-3

Question

I am new to fairly new to AS3 and I have found myself needing to extend a fla. that was written by a 3rd party.
The goal is to access flashvars but for the life of me can not get it to work...been at it for days learning..
the fla I am working with is code on timeline with 2 frames. the movieclip runs to frame 2 ans stops.
On frame 2 is where I require the use of the flashvar.
I have built a simple example that will populate a textbox on frame two that works fine.
frame 1
var my_var:String = new String();
my_var = root.loaderInfo.parameters.uploadId;
frame 2
my_txt.text = my_var;
stop();
However when I use the same approach on my 3rd party fla I get NULL output. I am not using any TLF text either (I think).
I don't understand why it works in one case but not the other. I am thinking it might have to do with conflict with the surrounding code but I don't know enough about AS to track it down. Any help on this would be greatly appreciated.

Answer 1

private var flashVarObj:Object = new Object;
flashVarObj=LoaderInfo(this.loaderInfo).parameters;
var my_var:String = new String();
my_var = flashVarObj.uploadIdd;
