Flash Button Linking and Toggle - actionscript-3

Question

Clicking one of 3 buttons shows price output in total.text
each button shows a different price.
code currently used for each button:
1 btn1.addEventListener(MouseEvent.CLICK, myButtonClick);
2
3 function myButtonClick(ev:MouseEvent):void
4 {
5 var a:Number = Number(99) * Number(1.2);
6 total.text = String(a);
7 }
8
9 btn2.addEventListener(MouseEvent.CLICK, myButtonClick);
10
11 function myButtonClick(ev:MouseEvent):void
12 {
13 var b:Number = Number(99) * Number(1.4);
14 total.text = String(b);
15 }
16
17 btn3.addEventListener(MouseEvent.CLICK, myButtonClick);
18
19 function myButtonClick(ev:MouseEvent):void
20 {
21 var c:Number = Number(99) * Number(1.6);
22 total.text = String(c);
23 }
24
it works fine, but i really want to Add the value of button 2 and/or 3 if toggled to the value of button 1 and display it in total.text
eventually, i am trying to get choice of 5 buttons to toggle 1 of. that toggle will set the initial Number(99) value with something..99 or what not. and then if i toggle 1 button in a second set of 5 buttons, it will set value in the second Number(1.2). and from there. the two toggled btn2 and btn3 would multiply total number in total.text.
i see where i can make a whole bunch of buttons with values calculated. but im sure there is a cleaner way to do that.
i am a total novice in flash and just kinda looking for a direction here. it would be awesome.
Edit: Did a little research. hope I'm heading in right direction
ok, added variable number like
var modifier1:Number = 99;
var modifier2:Number = 1.2;
then called on those from the function like
var a:Number = Number(modifier1) * Number(modifier2);
now researching on how to make the modifier1 actually link up to toggle state of a button and assign it a value like 99 for toggled and 1 for not.

I'd recommend creating a small class for all your buttons, it shall contain its value. You also need an object that will contain a list of these buttons, let's call it Application. When user clicks on Button1, it will set a field inside Application indicating the toggle - product of all values or just the button that was pressed. This then sets the actual text to whatever was passed (I've called it valueText).

Here's some quick code, I haven't tested if it actually works, but It should be pretty easy to follow:
class Button {
private var app:Application;
public var value:Number;
public function Button(app:Application, value:Number) {
this.app = app;
this.value = value;
this.addEventListener(MouseEvent.MOUSE_DOWN, mouseDown);
}
private function mouseDown(e:MouseEvent):void {
app.displayText(value);
}
}
class Application {
private var buttonList:Vector.<Button> = new Vector.<Button>();
public var isToggleOn:Boolean = false;
public function Application() {
buttonList.push(new Button(this, 0.98));
buttonList.push(new Button(this, 0.75));
buttonList.push(new Button(this, 0.88));
}
public function getProduct():Number {
var sum:Number = 0;
for(var button:Button in buttonList) {
sum += button.value;
}
return sum;
}
public function displayText(value:Number):void {
valueText.text = isToggleOn ? getProduct() : value;
}
}
