It is really hard to tell, without seeing the actual. project, but I am going to take a wild guess. I'm not sure what other state AnswerButton might be in, but if it is a built-in state, the top trigger won't work. All the built-in states are like the rest of us; they consider themselves to be perfectly normal. So if the button is in "Visited", for example, it will report itself as Normal, and this trigger won't fire.
If that doesn't help you, attach the .story file here to get some help specific to your problem.
