Help with left to right scrolling

Hi all,

I just don’t understand Actionscript, I’ve tried and I just don’t understand it. That being said, I have a movie that I’m making which has several product images. Initially the user sees about 7 product images and upon selecting either the left or right arrow the movie moves to show more products. I’ve looked at scrolling nav bars, but of course those don’t have a right or left arrow and I’ve looked at tutorials for up and down scrollers, but of course I can’t get it to move left or right.

Can someone help me figure out how to get this code to move the move left and right instead of up and down? Am I just going about this the wrong way? I don’t even need the scroller, just the left/right arrows (which currently are up/down).

scrolling = function () {
var scrollHeight:Number = scrollTrack._height;
var contentHeight:Number = contentMain._height;
var scrollFaceHeight:Number = scrollFace._height;
var maskHeight:Number = maskedView._height;
var initPosition:Number = scrollFace._y=scrollTrack._y;
var initContentPos:Number = contentMain._y;
var finalContentPos:Number = maskHeight-contentHeight+initContentPos;
var left:Number = scrollTrack._x;
var top:Number = scrollTrack._y;
var right:Number = scrollTrack._x;
var bottom:Number = scrollTrack._height-scrollFaceHeight+scrollTrack._y;
var dy:Number = 0;
var speed:Number = 10;
var moveVal:Number = (contentHeight-maskHeight)/(scrollHeight-scrollFaceHeight);

scrollFace.onPress = function() {
var currPos:Number = this._y;
startDrag(this, false, left, top, right, bottom);
this.onMouseMove = function() {
dy = Math.abs(initPosition-this._y);
contentMain._y = Math.round(dy*-1*moveVal+initContentPos);
};
};
scrollFace.onMouseUp = function() {
stopDrag();
delete this.onMouseMove;
};
btnUp.onPress = function() {
this.onEnterFrame = function() {
if (contentMain._y+speed<maskedView._y) {
if (scrollFace._y<=top) {
scrollFace._y = top;
} else {
scrollFace._y -= speed/moveVal;
}
contentMain._y += speed;
} else {
scrollFace._y = top;
contentMain._y = maskedView._y;
delete this.onEnterFrame;
}
};
};
btnUp.onDragOut = function() {
delete this.onEnterFrame;
};
btnUp.onRelease = function() {
delete this.onEnterFrame;
};
btnDown.onPress = function() {
this.onEnterFrame = function() {
if (contentMain._y-speed>finalContentPos) {
if (scrollFace._y>=bottom) {
scrollFace._y = bottom;
} else {
scrollFace._y += speed/moveVal;
}
contentMain._y -= speed;
} else {
scrollFace._y = bottom;
contentMain._y = finalContentPos;
delete this.onEnterFrame;
}
};
};
btnDown.onRelease = function() {
delete this.onEnterFrame;
};
btnDown.onDragOut = function() {
delete this.onEnterFrame;
};

if (contentHeight<maskHeight) {
scrollFace._visible = false;
btnUp.enabled = false;
btnDown.enabled = false;
} else {
scrollFace._visible = true;
btnUp.enabled = true;
btnDown.enabled = true;
}
};
scrolling();
