title: JQuery/HTML - 'undefined is not a function'
body: <p>My code isn't working and apparently it's because "undefined is not a function."</p>
  
  <p>What's wrong with the JQuery code I got here?</p>
  
  <pre><code>$(document).ready(function(){
      $("#contact").top("40%");
  });
  </code></pre>
