Coding Problems-help with AS3 quiz game

Ok, so could someone tell me what's wrong with this script?

stop();

Start_Game.addEventListener(Mous开发者_Go百科eEvent.CLICK, Start_function);

function Start_function(e:Event){ gotoAndPlay("Question Board"); }

stop();

Start_Game.addEventListener(MouseEvent.CLICK, Start_function);

function Start_function(e:MouseEvent){ gotoAndPlay("Question Board"); }

Instead of e:Event, write e:MouseEvent.
