Tween/AS preloader

I’ve just completed the Kirupa Tutorial for Tween/AS preloader.
http://www.kirupa.com/developer/actionscript/tween_as_preloader.htm

In the tutorial it adds frame actions to the end of preloader, specifying where to go next: SCENE2. Because I want to use this preloader more than once to load in different swf files, and other data. Do i need to create global variables for the different files i’m importing? and apply a diff variable each time I call on the preloader?

I’m a little lost.

Any advice would be appreciated.
