Help with enhanced scroller

i got a scroller which will play a movieclip called “anima2” when you drag the scrollbar. why will this script work when implemented in the main time line, but not in a movieclip?

function procesaRastro(v){
var count = 0;
this.onEnterFrame = function(){
if(count%2 == 0){
var uno = this[“anima”+count];
var dos = this[“anima”+(count+1)];
uno._x = this.scrollbar._x;
uno._y = this.scrollbar._y;
dos._x = this.scrollbar._x;
dos._y = this.scrollbar._y + (this.scrollbar._height-dos._height)+5;
delete this.onEnterFrame;

try adding _root before movie clip name?

i tried adding it but it helped nothing. i attached the fla so you can have a look.
