title: jQuery Accordion doesn't work
body: <p>I copied the code right from JQuery's website so I'm not sure what I'm missing. I'm new to JQuery so if anyone has any input, I'd appreciate it. I'm just trying to get the accordion working so I can get a better understanding of how to implement Jquery in projects that I am working on. I have tried writing my own methods but it usually takes too long and they don't work properly. So this is my first attempt at using one of JQuery's APIs and even this isn't working. I'm sure it's something stupid missing from my code but if someone could point me in the right direction, is there a general rule of thumb that is assumed when pulling code from JQuery that I'm missing somehow? I'm completely self-taught so I may have missed something really small but really important. Thanks in advance!</p>
  
  <p>Here's my code: </p>
