//open message box
btnPassport.addEventListener(MouseEvent.MOUSE_DOWN, btnPassportClicked);
function btnPassportClicked(event:MouseEvent):void {
	mcPassport.visible=true;	
}

//close message box wiht okay button within the movieclip.
mcPassport.btnOk.addEventListener(MouseEvent.MOUSE_DOWN, mcPassportOkClicked);
	function mcPassportOkClicked(event:MouseEvent):void {
		mcPassport.visible=false;		
	}

SimpleButton does not have a btnOk property. It looks like mcPassport is a SimpleButton. Are you trying to access a child of mcPassport? If so, you can use getChildbyName. Or, you could change mcPassport to a MovieClip, which is dynamic and flash will create the property corresponding to the child, as you seem to expect.
