how can i do this script work when it loads on other file?

Ex. the file with the script gonna load on the "main" file, but the movement of the movieclips doens't work.

The script i'm using is this:

onClipEvent (enterFrame) {
_root.navegacao._y+= (yy-_root.navegacao._y)/5;
_root.navegacao1._y+= (yy-_root.navegacao1._y)/5;
_root.navegacao2._y+= (yy-_root.navegacao2._y)/5;
_root.navegacao3._x+= (xx-_root.navegacao3._x)/5;
}

If anyone could help me?

when you say 'file' do you mean swf files? If so, reference stuff by _level. So the first movie loaded is: _level0.

So something like this:

onClipEvent (enterFrame) {
_level0.navegacao._y+= (yy-_level0.navegacao._y)/5;
_level0.navegacao1._y+= (yy-_level0.navegacao1._y)/5;
_level0.navegacao2._y+= (yy-_level0.navegacao2._y)/5;
_level0.navegacao3._x+= (xx-_level0.navegacao3._x)/5;
}
