There are a few ways you could approach this, so here's one. All code goes in the timeline where the buttons live (on the actions layer).

The only thing I am uncertain of is what I did with the scrollV in the scrollUp and scrollDown functions. I have not used this before, so I am assuming it is the same property that AS2 uses "scroll" for.

function scrollUp(evt:Event):void {
textbox.scrollV += 1;
}

function scrollDown(evt:Event):void {
textbox.scrollV -= 1;
}

function upOver(evt:MouseEvent):void {
stage.addEventListener(Event.ENTER_FRAME, scrollUp);
}

up_btn.addEventListener(MouseEvent.ROLL_OVER, upOver);

function upOut(evt:MouseEvent):void {
stage.removeEventListener(Event.ENTER_FRAME, scrollUp);
}

up_btn.addEventListener(MouseEvent.ROLL_OUT, upOut);

function downOver(evt:MouseEvent):void {
stage.addEventListener(Event.ENTER_FRAME, scrollDown);
}

down_btn.addEventListener(MouseEvent.ROLL_OVER, downOver);

function downOut(evt:MouseEvent):void {
stage.removeEventListener(Event.ENTER_FRAME, scrollDown);
}

down_btn.addEventListener(MouseEvent.ROLL_OUT, downOut);

Hi ned murphy,

thanks for ur reply.

i only have codes which are in as 1.0 and 2.0.

the code below is under actions: Frame1...

moveup = new Boolean();
movedown = new Boolean();
up_btn.onRollOver = function() {
    moveup = true;
};
down_btn.onRollOver = function() {
    movedown = true;
};
up_btn.onRollOut = function() {
    moveup = false;
};
down_btn.onRollOut = function() {
    movedown = false;
};

this is the codes under text box movie clip..

onClipEvent (enterFrame) {
    if (_root.moveup == true) {
        textbox.scroll += 1;
    }
    if (_root.movedown == true) {
        textbox.scroll -= 1;
    }
}

but i dunno how to change them to as3.

thanks murphy!
