Open the Properties Panel ( You should now see the Parameters of the ScrollPane Component).
Underneath where you see Component, give your ScrollPane an instance name.
I called mine ( ScrollPane ).
Click the Scroll Content parameter and type in the unique name of your movie clip ( myScrollableMovie )
You can also choose whether you want your Scrollpane to scroll Horizontal, Vertical or both.
Leaving Horizontal Scroll or Vertical Scroll to "auto" will assign scollbars if your ScrollPane is smaller
than the movie clip it is scrolling.

true = Please assign scrollbars and false = No scrollbars please.
