Help With Action Script 3.0 (ONLY ANSWER IF YOU KNOW FLASH WELL)?

ok i have 2 buttons:

button1

button2

now in the actionscript i typed:

stop();

button1.addEventListener(MouseEvent.CLICK, mouseDownHandler);

function mouseDownHandler(event:MouseEvent):void {

gotoAndStop(4);

}

button2.addEventListener(MouseEvent.CLICK, mouseDownHandler);

function mouseDownHandler2(event:MouseEvent):void {

gotoAndStop(2);

}

PROBLEM: button1 goes to frame 4. however so does button2. and vice-versa if i switch order of buttons. i need help from someone who knows flash.

additional info:

using Flash CS5.5

project is using AIR 2.6 for iOS

btw in the code it should be CLICK not CL.. yahoo answers is processing it wrong...
