Navigating Flash with Keyboard Arrows

Question

Hi,
I have a relatively simple request and I hope someone can help.
I need a flash file that plays 5 seperate movie clips in order and can be navitated using keyboard right and level arrows.
1. Flash File opens and stops
2. Keyboard right plays movie clip 1
3. Keyboard right again plays movie clip 2
However
3. Keyboard left jumps back and plays movie clip 1
I know this may seem simple, but Im new to flash and getting my head around action script and code snippets.
Thanks, in advance.
Chris.

Answer 1

I actually get this error
TypeError: Error #1010: A term is undefined and has no properties.
at Untitled_fla::MainTimeline/keydownF()
This is the code Im using and all my movie clips are named film1, film2 etc
/* Stop a Movie Clip
Stops the specified movie clip on stage.
Instructions:
1. Use this code for movie clips that are currently playing.
film2.stop();
film1.stop();
var nextFilmNum:int=-1;
var totalFilms:int = 2
stage.addEventListener(KeyboardEvent.KEY_DOWN,keydownF);
function keydownF(event:KeyboardEvent):void {
    switch (event.keyCode) {
        case 37 :
            if(nextFilmNum==-1){
                nextFilmNum=2;
                break;
            nextFilmNum=(totalFilms-1+nextFilmNum)%totalFilms
            break;
        case 39 :
            nextFilmNum=(nextFilmNum+1)%totalFilms
            break;
    this["film1"+(nextFilmNum+1)].play()
