Can I call a function (variable) with a deep nested button?

```auto

var sushi:Number = 1;

```

and then from a deep deep nested button within some movie clips :

```auto

button.addEventListener(MouseEvent.CLICK, sushiset);
function sushiset (event:MouseEvent):void{
    (root).sushi = 2;
}

```

recently I tried changing a movieclip just like this and it works with this code:

```auto

MovieClip(root).sushiMC.gotoAndPlay(1);

```

How will I do it \*\*in variables? \*\*Is it possible to **create a globally-used variable?**  
Thank you.
