help with text scrolling

[darth]

Hello,

I have made a scrollable textfield that can be scrolled with buttons and scrollbar
according to this tutorial - http://www.flashkit.com/tutorials/Interactivity/Actionsc-Patrick_-640/index.php

anyway, when I export to flash player 6 it works but when I export to flash player 7 the scrollbar doesn´t work. Actionscript 1.0 in both cases.

are there some new or changed properties for textfields in FMX 2004/FP7?
can I modify this script to make the scrollbar work?

actionscript -
onClipEvent (load){

//this.loadVariables("text.txt");
scrollbar._visible = false;
scrolling = 0;
frameCounter = 1;
speedFactor = 1;
numLines = 7;

origHeight = scrollbar._height;
origX = scrollbar._x;
needInit = false;

function initScrollbar(){

var totalLines = numLines + daTextBox.maxscroll - 1;
scrollbar._yscale = 1//00*(numLines)/totalLines;
deltaHeight = origHeight - scrollbar._height;
lineHeight = deltaHeight/(daTextBox.maxScroll - 1);
}
function updateScrollBarPos(){

scrollbar._y = lineHeight*(daTextBox.scroll - 1);
}
}

onClipEvent (enterFrame){

if( needInit ){
if(daTextBox.maxscroll > 1){
initScrollbar();
needInit = false;
}
}
if( frameCounter % speedFactor == 0){

if( scrolling == "up" && daTextBox.scroll > 1){
daTextBox.scroll--;
updateScrollBarPos();
}
else if( scrolling == "down" && daTextBox.scroll < daTextBox.maxscroll){
daTextBox.scroll++;
updateScrollBarPos();
}
frameCounter = 0;
}
frameCounter++;
}

onClipEvent (mouseDown){

if(up.hitTest(_root._xmouse,_root._ymouse)){
scrolling = "up";
frameCounter = speedFactor;
up.gotoAndStop(2);
}
if(down.hitTest(_root._xmouse,_root._ymouse)){
scrolling = "down";
frameCounter = speedFactor;
down.gotoAndStop(2);
}
if(scrollbar.hitTest(_root._xmouse,_root._ymouse)) {
scrollbar.startDrag(0,origX,deltaHeight,origX);
scrolling = "scrollbar";
}
updateAfterEvent();
}

onClipEvent (mouseUp){

scrolling = 0;
up.gotoAndStop(1);
down.gotoAndStop(1);
stopDrag();

updateAfterEvent();
}

onClipEvent (mouseMove){
if(scrolling == "scrollbar"){
daTextBox.scroll = Math.round((scrollbar._y)/lineHeight + 1);
}
updateAfterEvent();
}

/*onClipEvent (data){
needInit = true;
}*/
