Вот ввожу код:

var btn1:button1 = new button1();
addChild(btn1);
btn1.alpha = 0.5;
btn1.addEventListener(Event.ENTER_FRAME,f1btn1);
function f1btn1(e:Event):void
{
	btn1.x = 275;
	btn1.y = 75;
}
btn1.addEventListener(MouseEvent.MOUSE_OVER,f2btn1);
function f2btn1(Event:MouseEvent):void
{
	btn1.alpha = 1;
}
btn1.addEventListener(MouseEvent.MOUSE_OUT,f3btn1);
function f3btn1(Event:MouseEvent):void
{
	btn1.alpha = 0.5;
}
btn1.addEventListener(MouseEvent.CLICK,f4btn1);
function f4btn1(Event:MouseEvent):void
{
	removeChild(btn1);
	removeChild(btn2);
	removeChild(btn3);
	gotoAndStop(2);
}
var btn2:button2 = new button2();
addChild(btn2);
btn2.alpha = 0.5;
btn2.addEventListener(Event.ENTER_FRAME,f1btn2);
function f1btn2(e:Event):void
{
	btn2.x = 275;
	btn2.y = 200;
}
btn2.addEventListener(MouseEvent.MOUSE_OVER,f2btn2);
function f2btn2(Event:MouseEvent):void
{
	btn2.alpha = 1;
}
btn2.addEventListener(MouseEvent.MOUSE_OUT,f3btn2);
function f3btn2(Event:MouseEvent):void
{
	btn2.alpha = 0.5;
}
btn2.addEventListener(MouseEvent.CLICK,f4btn2);
function f4btn2(Event:MouseEvent):void
{
	removeChild(btn1);
	removeChild(btn2);
	removeChild(btn3);
	gotoAndStop(3);
}
var btn3:button3 = new button3();
addChild(btn3);
btn3.alpha = 0.5;
btn3.addEventListener(Event.ENTER_FRAME,f1btn3);
function f1btn3(e:Event):void
{
	btn3.x = 275;
	btn3.y = 325;
}
