how do i organize my dynamic text field so i can determine how the text is displayed and how much you have to scroll to view it entirely

ive been trying to display a small portion of my text in the swf to reserve space but flash always displays the text differently then how i want it to be

i simply made two buttons with the
on (press) {welcome.scroll +(-)=1 }

i cant manage to display the text the way i want it

any advice will be appreciated
