Simple scroll bar tutorial

I followed this tutorial http://www.kirupa.com/developer/flash8/scrollbar.htm

My question is how would i change the initial postion of the content and the scroll bar to start in the middle?

heres a diagram

------------------------^

blah balh blah
blah blah blah
Middle of the content-- [ ]
blah blah blah
blha blha blha
blah blah blah

-----------------------^

bump, c’mon i made a kick *** diagram.

can anyone say *bump

After taking a brief look at the tutorial I would mess around with the init variables for the scroller:

var initPosition:Number  = scrollFace._y=scrollTrack._y;
var initContentPos:Number = contentMain._y;

Serkios, thanks for trying, but it didn’t work.
