[f8]Keep track of the current page

[jsfaulds]

Hi hope someone can help

On the stage, i have three buttons called, button1,2,3 In the Library, I have three movie clips called, page1 page2 page3.
When the movie loads page1 is loaded and when you click on button2 page1 fades out and page2 fades in
Then press on button1, page2 fades out and page1 fades back in again.
All's well with the code and two buttons.

My problem is when i try to add button3 I cant get the current page code to work.
At the moment all the ( var currentPage = "page1"; ) code is doing is stoping the current page fading in again when your on that page.

could someone help with some code that will Keep track of the current page

This is the code for the two buttons

import mx.transitions.Tween;
import mx.transitions.easing.*;
var currentPage = "page1";

var page1:MovieClip = this.attachMovie("page1","page1",10);
page1._x = Stage.width/2;
page1._y = Stage.height/2;


button1.onRelease = function() {
if(currentPage !="page1") {
var fadeout:Tween = new Tween(page2,"_alpha",Strong.easeOut,100,0,1,true);
fadeout.onMotionFinished = function() {
var page1:MovieClip = _root.attachMovie("page1","page1",10);
page1._x = Stage.width/2;
page1._y = Stage.height/2;
page1._alpha = 0;

var fadein:Tween = new Tween(page1,"_alpha",Strong.easeOut,0,100,1,true);
currentPage = "page1";
}
}
}

button2.onRelease = function() {
if(currentPage !="page2") {
var fadeout:Tween = new Tween(page1,"_alpha",Strong.easeOut,100,0,1,true);
fadeout.onMotionFinished = function() {
var page2:MovieClip = _root.attachMovie("page2","page2",10);
page2._x = Stage.width/2;
page2._y = Stage.height/2;
page2._alpha = 0;

var fadein:Tween = new Tween(page2,"_alpha",Strong.easeOut,0,100,1,true);
currentPage = "page2";
}
}
}
