Grabbing a variable in a function from an external swf

Hey all,

I need to trace out the variable currentClip from the following code that is in an external swf. The parent swf calls the external swf empty_mc via loadclip.
[AS]
function setNextClip():Void
{
currentClip = clipArray[iterator];
iterator++;
currentClip._visible = true;
fadeIn();
}
[/AS]
Any help is greatly appreciated!
