Scroll problemo in AS3... anyone, pls?

programming flash
1

Hi there!
I am using this code to create a scrollbar in a text field in frame 1.
Everything is working nice.
But rather than just clicking on the arrows of the scroll bar, i would like that, when reached frame 20, it will scroll by itself.
I tried by adding 5 to the textBox.y but that was just moving the text block up or down. Wasnt SCROLLING at all! Just moving the text block.
Can anyone give me a clue how to scroll using just as3 ? :confused:
Thanks.
Cheers.
Leo.


textBox.htmlText = textBox.text;
 
 //sets up the scrollbar
 var vScrollBar:UIScrollBar = new UIScrollBar();
 vScrollBar.scrollTarget = textBox;
 vScrollBar.height = textBox.height;
 vScrollBar.move( textBox.x + textBox.width, textBox.y );
 addChild(vScrollBar);
 vScrollBar.update();
