dynamic scrolling text

I think I did not understand you

What do you expect it to do? Where the new text is coming from?

Hi,
I tried to do what you said and it is working,
I made a movie clip named m1 inside it movie clip named m2 and inside it the dynamic text insde it named Text and I had animated m2 using the time line.

I created a button to change the text named B1 and this is the code and it is working:

m1.m2.Text.text="5555";
B1.addEventListener(MouseEvent.CLICK,ff);
var i:Number=new Number;
function ff(event:MouseEvent) {
//to change the text
if (i==0) {
m1.m2.Text.text="444";

} else {
m1.m2.Text.text="43333334";
}
i++;
}
