Dynamic text

1

Hi,
I wrote a code that’s suppose to change the number in a synamic text whn I press a button,<br>What did I do wrong?

Object(root).currentNum=1;
Object(root).pageNum.text = Object(root).currentNum;
Object(root).arrowLeft.addEventListener(MouseEvent.CLICK, arrowLeftClick);
function arrowLeftClick (e:MouseEvent):void{
Object(root).currentNum-=1;
}

now it’s only showing me the number 1.
