Multiple Buttons help needed

Question

Hey everyone,
I am just beginning to learn the basics of creating web sites in flash.
I have been following a tutorial and have it done pretty well, but they only cover one main button, and I am at the point where I need several more, but I am doing something wrong.
The tutorial is at this page: http://www.flash-game-design.com/flash-tutorials/advancedWebsite-flash-tutorial-3.html
You can skip to the end and download the .fla if you want.
What I want to do specifically is to add probably 4 other main buttons that can also have drop down menus. Please be as specific as possible because the extent of my code knowledge isn't very far.
Thanks in advance
The code for the main page is as follows:
menu = ["About", "Bio", "Contact"];
this.createEmptyMovieClip("content", 1000);
this.attachMovie("sectionBackground","mask",1001);
mask._y = content._y=208;
mask._x = target=68;
content.setMask(mask);
content._x = -1000;
imageScrollSpeed = 5;
xStart = 125;
yStart = 51;
bWidth = 79;
bHeight = 17;
interval = 50;
countDown = menu.length;
menuOpen = false;
theTime = 0;
buttonScrollSpeed = 2;
for (var i = 0; i<menu.length; i++) {
var section = content.attachMovie("section_"+menu[i], "section_"+menu[i], i+100);
section._x = section._width*i;
var b = this.attachMovie("subButton", "subButton"+i, countDown);
countDown--;
b.stop();
b._x = xStart;
b._y = ySwtart;
b.interval = interval*i;
b.target = yStart+(bHeight*i);
b.txt = menu[i];
b.pos = target+(i*-section._width);
b.onPress = function() {
  target = this.pos;
  closeMenu();
  this.gotoAndStop(1);
b.onRollOver = function() {
  this.gotoAndStop(2);
b.onRollOut = function() {
  this.gotoAndStop(1);
b._visible = false;
function closeMenu() {
for (var i = 0; i<menu.length; i++) {
  var b = this["subButton"+i];
  b._visible = false;
  b._x = xStart;
  b._y = yStart;
menuOpen = false;
mainButton.onPress = function() {
if (!menuOpen) {
  theTime = getTimer();
  menuOpen = true;
  for (var i = 0; i<menu.length; i++) {
   _root.main["subButton"+i]._visible = true;
} else {
  closeMenu();
mainButtoncopy.onPress = function() {
if (!menuOpen) {
  theTime = getTimer();
  menuOpen = true;
  for (var i = 0; i<menu.length; i++) {
   _root.main["subButton"+i]._visible = true;
} else {
  closeMenu();
function scrollButtons() {
if (menuOpen) {
  for (var i = 0; i<menu.length; i++) {
   var b = this["subButton"+i];
   if ((theTime+b.interval)<getTimer()) {
    b._y += (b.target-b._y)/buttonScrollSpeed;
this.onEnterFrame = function() {
content._x += (target-content._x)/imageScrollSpeed;
scrollButtons();
