POM's sliding menu in its own swf

I have two sliding menus in the same movie, and they interfere with one another if they’re movie clips. So for the second one, it is in a swf and I’m using loadMovie to play it. That works fine, but there are mcs inside the swf, and I cannot seem to access them.

Does anyone either 1. know how to utilize two of these sliding menus so they behave independently, or,

  1. know how to access clips inside the sliding menu in its own swf? Here’s what I’ve tried so far:
thumbs_home.loadMovie("scrollingwindow2.swf");
thumbs_home._x = 50;
thumbs_home._y = 0;

this.onEnterFrame = function(){
    if(thumbs_home.getBytesLoaded() >= thumbs_home.getBytesTotal() && thumbs_home.getBytesLoaded() > 4){
        thumbs_home.th_general.ae_t_mc._alpha = 40;
       
        delete this.onEnterFrame;
    }
};

SWF code attached.
Thanks!
