Thats the script, I hope this tutorial was helpful. Now try to improve it and add more features in to it. Some ways to improve it, off the top of my head are;
Have the background scroll area for the scroller have mcs in it that will move the scroller to its location when you press it.
Put some buttons on the top and bottom to move the scroller up and down
Make some buttons that will load a different movie into the content movie clip
Put a dynamic text box in the content movie clip and use loadVariables() to import some html into it
Make the scroller change its size based on the height of the content being scrolled
