Buttons moving on top of panorama

Question

Hi,
I have a panorama which I've coded to move back and forth horizontally when I press the arrow keys. I'm trying to get some buttons to sit at designated points across the panorama. I'm having trouble getting them to stick at the right places, though, instead of roaming around. Right now, I'm focusing on Norris_btn (although Annenberg_btn doesn't work right now either), which starts out in the right position (all the way at the far left of the panorama, which is 10061 px wide). However, if I scroll all the way to the right and then try and go back to the left, Norris_btn appears in the wrong place. Here is my code:
const PANWIDTH:Number=10061
const STAGEWIDTH:Number=650
const KEYWIDTH:Number=40
//positions objects on the stage
panorama_mc.x = 0;
Norris1_btn.x=-5030.5;
Norris1_btn.y=0;
Annenberg_btn.x=-1145;
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);
stop();
function keyPressed (event:KeyboardEvent):void {
            switch (event.keyCode) {
        case  Keyboard.LEFT :
           if (panorama_mc.x + KEYWIDTH<=(PANWIDTH / 2) - (STAGEWIDTH / 2)) panorama_mc.x +=KEYWIDTH;
           if (Norris1_btn.x + KEYWIDTH <=-(STAGEWIDTH/ 2)) Norris1_btn.x += KEYWIDTH;
                              if (Annenberg_btn.x<=(PANWIDTH / 2) + KEYWIDTH) Annenberg_btn.x += KEYWIDTH;
           break;
        case  Keyboard.RIGHT :
           if (panorama_mc.x - KEYWIDTH>=-(PANWIDTH / 2) + STAGEWIDTH) panorama_mc.x -= KEYWIDTH;
                              if (Norris1_btn.x - KEYWIDTH >=-(PANWIDTH / 2) + STAGEWIDTH) Norris1_btn.x -= KEYWIDTH;
           if (Annenberg_btn.x>=(-PANWIDTH / 2) + KEYWIDTH + STAGEWIDTH) Annenberg_btn.x -= KEYWIDTH;
Any suggestions? Thanks!

I had tried to do that, but after a lot of searching around and trying out different things I'm still a little bit unsure of how to make it so AS can talk to the button when it's a part of the movie clip.
RIght now I have this in the main timeline:
panorama_mc.Norris1_btn.addEventListener(MouseEvent.CLICK, showNorris);
function showNorris (event:MouseEvent):void
          gotoAndStop(2);
and this in the movie clip timeline:
Norris1_btn.addEventListener(MouseEvent.CLICK, showNorris);
function showNorris(event:MouseEvent):void
          gotoAndStop(2);
But I get an error 1009 for a null object reference and the panorama won't move. What am I doing wrong?
