Controlling mc's in a different movie

[Reign2000]

I've got a movie that loads with loadMovie. What I need help with is manipulating the mc's in the loaded movie from the original movie. Both timelines are one frame, (all actionscript). I'm using Flash MX, I'd appeciate any help. Thank you.

Is this a relative path question? Cause if it is; When u create a movieclip in root named SomeCoolMovieClip then its path will be _root.SomeCoolMovieClip. if u want to make a movieClip in that movieClip; try
_root.SomeCoolMovieClip.createEmptyMovieClip("even CoolerMovieClip", someCoolDepth);

Now u can control that movieClip from the root by addressing it as SomeCoolMovieClip.evenCoolerMovieClip.alpha = 10 (for instance), u could adress it from inside of SomeCoolMovieClip via evenCoolerMovieClip (since it is it's direct child). Any movieClip can call it by using its full path (_root.someCoolMovieClip.evenCoolerMovieClip).

i hope this is a little clearer.
