Creating a ScrollBar in AS3

Hi all!

I´ve been having some difficulties creating a ScrollBar in AS3, as with most other things coming from AS2. I´m getting desperate, which is why I joined this forum looking for help!

What I would like to do, is to create a simple Scroll to a textfield and put my own design to the bars, something like the scroll on the bottom left on http://www.waytion.com/

Anyone who can help me out here?
