我知道这个问题被发布了一百万次，我阅读了所有的答案，但我仍然无法弄清楚我的游戏中的问题出在哪里，我遇到了这个错误
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at habitadnew_fla::MainTimeline/frame2()
at flash.display::MovieClip/gotoAndStop()
at habitadnew_fla::MainTimeline/fl_ClickToGoToAndStopAtFrame_11()
我一次又一次地构建我的电影剪辑和我的按钮，但我仍然收到这个错误。你能帮我么。我是闪光灯新手。如果有人想查看我的代码，我将我的游戏上传到http://snk.to/f-ctpm6nj1。
谢谢
