Bootstrap Collapsible Menu not working

Question

I'm having an issue getting the collapsible navigation bar to load on a page - the button appears when you shrink the screen, but when I click on it, nothing happens. The console isn't throwing me any errors, so I'm assuming there must be something wrong with my css/javascript, but I don't really know what.

If it matters, I'm linking through with the Bootstrap CDN on my page - I don't know if that requires me to include the plugins manually or not (I don't think it would but I'm not sure).

The following is my HTML and Javascript link-ins:

 <div class="navbar-header">
    <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="navbar-collapse">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
  </div>

  <!-- Collect the nav links, forms, and other content for toggling -->
  <div class="collapse navbar-collapse">
    <ul class="nav navbar-nav">
      <li class="active"><a href="/">Home</a></li>
      <li><a href="#">Operation Pulse</a></li>
      <li><a href="#">Forum</a></li>
      <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Media <b class="caret"></b></a>
        <ul class="dropdown-menu">
          <li><a href="news/">News &amp; Updates</a></li>
          <li><a href="#">Indie Pulse</a></li>
          <li><a href="#" style="text-transform: lowercase;">rec</a></li>
          <li><a href="#">Geeks and Giggles</a></li>
          <li class="divider"></li>
          <li><a href="#">Podcasts</a></li>
        </ul>
      </li>
      <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Info <b class="caret"></b></a>
        <ul class="dropdown-menu">
          <li><a href="#">About Us</a></li>
          <li><a href="#">FAQ</a></li>
          <li><a href="crew.php">Crew</a></li>
          <li><a href="contact.php">Contact Us</a></li>
        </ul>
      </li>
    </ul>
  </div>

JS

<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.2/css/bootstrap.min.css" rel="stylesheet">
    <!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
    <script src="//code.jquery.com/jquery.js"></script>
    <!-- Include all compiled plugins (below), or include individual files as needed -->
    <script src="//netdna.bootstrapcdn.com/bootstrap/3.0.2/js/bootstrap.min.js" type="text/javascript"></script>

Change the data-target= in the button to.. .navbar-collapse

<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
