Compiler Error: 1120 / 1067. please help!

Question

I've been stuck on this error for a whole day now, trying to find out whats wrong. im new to AS3, but i have been following the tutorials with lynda.com
i've been trying to make a scrollbar and everything works fine, until i have to connect it with the text. theres an image and a title that i want to scroll with the (static) text so i created a movie clip (instance name cafe_txt), and when i wrote the script and tested the movie, i come up with the 1120 error that cafe_txt is not defined.
So i changed the clip(thinking that the problem was the scrollbar had to be in the same instance as the text) so that the scrollbar was inside, and i come up with error 1067(1067: Implicit coercion of a value of type flash.display:MovieClip to an unrelated type flash.text:TextField.)
I've tried changing names, double checking that instance names are correct, moving things, changing the text so that its dynamic not static(if the scrollbar is connected to just the dynamic text it works, it just doesnt scroll the full length of the text)
here's the code in my stage:
scrollbar_mc.textField = cafe_txt
and my code from the scrollbar.as file:
package com.lynda.ui
    import flash.display.*;
    import flash.events.*;
    import flash.geom.Rectangle;
    import flash.text.TextField;
    public class Scrollbar extends Sprite
        public var value:Number;
        public var padding:Number = 5;
        private var _textField:TextField;
        private var max:Number;
        private var min:Number;
        public function Scrollbar()
            min = bar_mc.y;
            max = bar_mc.height - drag_mc.height;
            drag_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragHandle);
        private function dragHandle(event:MouseEvent):void
            drag_mc.startDrag(false, new Rectangle(0,min,0,max));
            stage.addEventListener(MouseEvent.MOUSE_UP, stopDragging);
            stage.addEventListener(MouseEvent.MOUSE_MOVE, updateValue);
        private function stopDragging(event:MouseEvent):void
            drag_mc.stopDrag();
            stage.removeEventListener(MouseEvent.MOUSE_UP, stopDragging);
            stage.removeEventListener(MouseEvent.MOUSE_MOVE, updateValue);
        private function updateValue(event:MouseEvent=null):void
            value = (drag_mc.y - min) / max;
            if(_textField && event)
                _textField.scrollV = Math.ceil(value * _textField.maxScrollV);
            dispatchEvent(new Event(Event.CHANGE));
        public function set textField(tf:TextField):void
            _textField = tf;
        public function get textField():TextField
            return _textField;
thanks for the help...

click file/publish settings/flash and tick "permit debugging".  retest.  the problematic line of code will be listed in the error message.
