FirefoxOS App

I got the structure of my app working which I think was mostly due to an unclosed div and I added a few touches like a back button. So what I'm working on my app now is being able to move a div using buttons but obviously the phone won't have a keyboard so I have to make my own buttons. I thought it was going to be pretty easy but I have no idea why my code isn't working. I'm just saying that if one id is clicked, another id should be animated but I can't figure out the problem.
