Scroller that loads into another movie

Hi!
I have a problem with some Actionscript…
I have a horisontal scroller that works fine when its used without it loading into another movieclip.
I have a master file that loads in that scroller swf file, i think it has some errors with the paths… but I´ve tried various ways to get it to work, but no sucess.
I have three objects on stage, the content mc with AS:
onClipEvent(enterFrame) {
_root.scrollMC._x=-1*(_root.slider.b);
}

And then the sliderpath with as:
onClipEvent (load) {
setProperty (this, _x, _root.slider._x);
setProperty (this, _y, _root.slider._y);
}

Finally the scrollerbar with as:
onClipEvent (load) {
setProperty (this, _y, int(_y));
}
onClipEvent (enterFrame) {
a = new Object();
a.y =this._y;
a.x =this._x;
_root.path.globalToLocal(a);
b=int(a.x*2);
}

Do u know what I need to change for the scroller to work when its loaded into another swf?
Cheers!
