Eey,

I'm not sure I understand your (entire) threat, but this is what I can tell about variables in flash:

Localization is done by _levels and by instance_names

So variables in level0 are like /:var or _level0/:var

Variables in movieclips which are in level0 are like /movieclipname:var or _level0/movieclipname:var

Variables in swf's which are for example loaded into some movieclip which is embedded in a second movieclip which is located in level12 are defined as _level12/secondmovieclipname/movieclipname:var

LTr'Z!
