Help making Flash 7 AS2 code working on all Flash versions

Hello :slight_smile:

I did this AS2 code in Flash CS4 and have a little trouble with it.

if (as2_mc.text != "Using Actionscript 2") {
	_root.createEmptyMovieClip("dynamic_mc",1);
	_root.dynamic_mc.beginFill(0x000000);
	_root.dynamic_mc.moveTo(0,0);
	_root.dynamic_mc.lineTo(Stage.width,0);
	_root.dynamic_mc.lineTo(Stage.width,Stage.height);
	_root.dynamic_mc.lineTo(0,Stage.height);
	_root.dynamic_mc.lineTo(0,0);
	_root.dynamic_mc.endFill();
	_root.dynamic_mc._x = 0;
	_root.dynamic_mc._y = 0;
	_root.createTextField("dynamic_txt",2,0,0,150,1);
	_root.dynamic_txt.text = "Not using Actionscript 2";
	var textstyle:TextFormat = new TextFormat();
	textstyle.color = 0xffffff;
	textstyle.size = 16;
	textstyle.font = "Arial";
	textstyle.align = "center";
	_root.dynamic_txt.setTextFormat(textstyle);
	_root.dynamic_txt.autoSize = true;
	_root.dynamic_txt.multiline = true;
	_root.dynamic_txt.wordWrap = true;
	_root.dynamic_txt._x = (Stage.width-_root.dynamic_txt._width)/2;
	_root.dynamic_txt._y = (Stage.height-_root.dynamic_txt._height)/2;
}

It works like I want it to in Flash 7 and looks like this, but when I change the publish settings into Flash 8/9/10, the code looks like [url=http://www.fhqhosting.com/ui/as2_f10.swf]this.

How do I make the code work on all AS2 Flash versions?
