Creating a scroll bar

hey there kirupas!
i’m having som problems creating a scroll bar…
i didnt want to use the default component, so i’ve made my one, but can’t make it work…cause i’m missing the actions.
it has no up and down buttons, just the middle bar…

so, my question is what scripting should i use to move my text up and down?

the scroll text i have has the instance name scrolltext. i’ve converted it to a movie (is it wrong?) and created a mask around it.

whow can i make the scrolling?

and thanks in advance!
