AS3 to AS2 code

Question

Hello,  I have a problem with a small code.
I'm doing a photo gallery in as3 to insert into my website, the problem is that my site is made in as2 and when I insert the gallery into website the up and down buttons don´t work. Someone could tell me how to modify this code ? I need the code in AS2. Thanks
stop ();
var arriba = Boolean;
var abajo = Boolean;
//scroll
abajobtn.addEventListener (MouseEvent.MOUSE_DOWN, mover_abajo);
function mover_abajo (event:MouseEvent) :void {
  abajo = true;
arribabtn.addEventListener (MouseEvent.MOUSE_DOWN, mover_arriba);
function mover_arriba (event:MouseEvent) :void {
  arriba = true;
addEventListener (Event.ENTER_FRAME, mover);
function mover (event:Event) :void {
  if (abajo == true) {
  if (tiravip.y >= -965) {
  tiravip.y -= 12;
  if (arriba == true) {
  if (tiravip.y <= 7) {
  tiravip.y += 12;
abajobtn.addEventListener (MouseEvent.MOUSE_UP, detener_abajo);
function detener_abajo (event:MouseEvent) :void {
  abajo = false;
arribabtn.addEventListener (MouseEvent.MOUSE_UP, detener_arriba);
function detener_arriba (event:MouseEvent) :void {
  arriba = false;

Ned, thanks for answering.
I tried with this code and doesn´t work. Do you know why ?
stop ();
var arriba = Boolean;
var abajo = Boolean;
//scroll
abajobtn..onMouseDown = mover_abajo;
function mover_abajo () :void {
  abajo = true;
arribabtn..onMouseDown = mover_arriba;
function mover_arriba () :void {
  arriba = true;
addEventListener (Event.ENTER_FRAME, mover);
function mover (event:Event) :void {
  if (abajo == true) {
  if (tiravip._y >= -965) {
  tiravip._y -= 12;
  if (arriba == true) {
  if (tiravip._y <= 7) {
  tiravip._y += 12;
abajobtn..onMouseUp = detener_abajo;
function detener_abajo () :void {
  abajo = false;
arribabtn..onMouseUp = detener_arriba;
function detener_arriba () :void {
  arriba = false;
