Transitions Between External SWFs - _root problem

I know that there are couple of similar threads regarding same tutorial and similar problems but noone explains what to do in such situation… so here it goes

I know that it isn’t very hard to do but probably I’m just stupid…

Lets say I got everything like in that tutorial [ http://www.kirupa.com/developer/mx2004/transitions.htm ] except that my container is not on main timeline but in another movieClip that is placed on the main timeline [Scene1 - movieClip - container].
Now as I clik on my buttons [they are placed in that movieClip too] I can see the transitions [intro and outro] but I got THE SAME .swf loading over and over again [same as I stated in my variable at the beggining f.e: currMovie = “section1”; will load section1 over and over no matter what button will I click].

Please help me with this cause I tried using, _root, _parent, _global, this, in many different ways but I can’t get it working…

I will be very gratefull for any help cause its the 3rd day I’m trying to fix it…

P.S. Please remember that the code that loads new .swf to the container is in .swf already loaded ! So do I have to change exactly this line ? f.e: _root.container.loadMovie(_root.currMovie+".swf"); [that is placed in external .swf’s ]
