The actionscript below is the code of dynamic text with the scroll bar, and has only seven lines in text scrolling area, but I would like to increase more lines, and its width.Scale on dynamic text box it doesn't work. Please advise.

Thank you,
Kathryn

onClipEvent (load){

this.loadVariables("text.txt");
scrolling = 0;
frameCounter = 1;
speedFactor = 3;
numLines = 7;
resetOnNewFile = true;

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

refreshRate = 12;
refreshCounter = 0;
refreshlastMaxscroll = 0;
loaded = false;

function refreshScrollBar(){

daTextBox.scroll = resetOnNewFile ? 1 : Math.min(daTextBox.maxscroll, daTextBox.scroll);

var totalLines = numLines + daTextBox.maxscroll - 1;
scrollbar._yscale = 100*(numLines)/totalLines;
deltaHeight = origHeight - scrollbar._height;
lineHeight = deltaHeight/(daTextBox.maxScroll - 1);
scrollbar._y = lineHeight*(daTextBox.scroll - 1);

}

function updateScrollBarPos(){

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

onClipEvent (enterFrame){

if( loaded ){

if(refreshCounter % refreshRate == 0 && daTextBox.maxscroll != refreshLastMaxScroll){

refreshScrollBar();
refreshLastMaxScroll = daTextBox.maxscroll;
refreshCounter = 0;

}
refreshCounter++;
}

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){
loaded = true;
}
