Question regarding multidimensional array for navigation bar

I'm using a multidimensional array to create a basic nav bar for a website i've been working on for a while.. I'm still very much a "noob" to programming, which is most likely the reason for the concussion I've sustained from repeatedly slamming my head against my desk.;)

anyway my problem is that i can't figure out how to "target" the specific buttons in my sub-menu (the drop down).. I've figured out how to target the buttons as a whole (as in when i use a trace command, they all perform identically, ((the sub menu vs, the primary))) ...

I'm also having a wee bit of trouble with rollover effects, but at the moment they are the least of my concern... I need to know what i need to do to, say, make it so the "accessories" button either initiates a loadMovieNum() or getURL command.... I appreciate any help anyone can offer, and I also appreciate all the help which has been provided in the past...

I've pasted the code below,

#include "lmc_tween.as"
// ### Array and Variables ### \\
var menu_arr:Array = new Array([["Home"], "home"], [["Motorcycles", "Parts", "Accessories", "Gear", "Store"], "inst"], [["Quads", "Parts", "Accessories", "Gear", "Store"], "Go To Store"], [["Department", "Water Sports", "Toy Haulers", "Fu"],"page"], [["Contact", "Location", "Email"],"contact"]);
//var menu_arr:Array = new Array([["Home"], "home"], [["Instructions", "how", "what", "where", "fuck it"], "inst"], [["Play Game", "who", "why"], "playGame"], [["Create Character"], "create"], [["Quit Game"], "quit"]);\\
// ### Functions ### \\
function makeMenu() {
for (var i:Number = 0; i < menu_arr.length; i++) {
var newName:MovieClip = this.attachMovie("item_mc", menu_arr[1] + "_mc", this.getNextHighestDepth());
newName._alpha = 0;
var newX:Number = Math.abs((newName._width + 15) * i);
newName._x = Stage.width + 200;
newName._y = 50;newName.id = i; // Refers to current array index.
newName.slideTo(newX, "_y", 2, "linear", i / 8);
newName.alphaTo(100, 2, "linear", i / 8);
newName.item_txt.text = menu_arr[0][0];
newName.onRollOver = function() {
makeSubMenu(this.id, this._x);
}
newName.onRelease = function() {
trace(this.id);
}


}
}


function makeSubMenu(mainId, mainX) {
container_mc.removeMovieClip();
this.createEmptyMovieClip("container_mc", this.getNextHighestDepth());
for (var i:Number = 1; i < menu_arr[mainId][0].length; i++) {
//trace(i);
var newSub:MovieClip = container_mc.attachMovie("item_mc", "sub" + i + "_mc", i);
newSub._x = mainX;// Math.abs(mainX + ((newSub._width + 2) * (i - 1)));
newSub._y = Math.abs(100 + ((newSub._height + 2) * (i - 1)));
newSub.item_txt.text = menu_arr[mainId][0];
newSub._alpha = 0;
newSub.alphaTo(100, 1, "linear");
newSub.onRollOver = function(){
this.gotoAndPlay(2);
}
newSub.onRollOut = function(){
gotoAndPlay(1);
}


newSub.onRelease = function(){
trace("this button werks d**che bag...");
}
}
}
//newName.onRollOut = function(){
//  this.newSub.alphaTo(0, 1, "linear", 0);
//}
makeMenu();
