Error evaluating frame script - swf to HTML5 conversion

Dear Friends,

Iam new to Haxe, iam a Actionscript3 programmer, i have some elearning lessons as swf&fla. I want to convert it as html5 and run in the browser. i followed the instruction and created one sample. My swf loads fine as html. But when there is a simple action script it throgh the eror as below:

[swf.exporters.animate.AnimateTimeline] Error evaluating frame script
TypeError: Cannot read property ‘addEventListener’ of undefined


this.btn2.addEventListener(openfl_events_MouseEvent.CLICK, this.btn1Clicked);}

Actually i just copy and pasted my moviecps elements all in side layout.fla.

my code in animate is (timeline inside a movieclip):

btn2.addEventListener(MouseEvent.CLICK, btn1Clicked);
function btn1Clicked(event:MouseEvent){

my code in prject.xml:

<?xml version="1.0" encoding="utf-8"?>
<meta title="Simple SWF Layout" package="org.openfl.samples.simpleswflayout" version="1.0.0" company="OpenFL" />
<app main="Main" path="Export" file="SimpleSWFLayout" />
<source path="Source" />
<haxelib name="openfl" />
<haxelib name="layout" />
<haxelib name="swf"/>
<library path="Assets/layout.swf" generate="true" preload="true" />

my code in Main.hx:
import layout.Layout;
import layout.LayoutItem;
import openfl.display.MovieClip;
import openfl.display.Sprite;
import openfl.utils.ByteArray;
import openfl.Assets;
class Main extends Sprite {
private var clip:MovieClip;
private var layout:Layout;

public function new () {
	super ();
	var timeline = Assets.getMovieClip("layout:");
	clip = Assets.getMovieClip ("layout:Layout");
	addChild (clip);
	layout = new Layout ();
	layout.addItem (new LayoutItem (clip.getChildByName ("Background"), STRETCH, STRETCH, false, false));
	layout.addItem (new LayoutItem (clip.getChildByName ("Header"), TOP, STRETCH, true, false));
	layout.addItem (new LayoutItem (clip.getChildByName ("Column"), STRETCH, LEFT, false, true));
	layout.resize (stage.stageWidth, stage.stageHeight);
	stage.addEventListener (Event.RESIZE, stage_onResize);
private function stage_onResize (event:Event):Void {
	layout.resize (stage.stageWidth, stage.stageHeight);	


i just tried to stop, when we click on a button it should play… Please help me to do this. i have more swf files to convert as html5.

I have voice over in my flash file, its not playing in HTML5 after compile. i did openfl test html5.

please help me to solve this.
