    <li><a href="#page5">Page 5</a></li>
  </ul>
</nav>

<div data-spy="scroll">
  <section id="page1" class="page">
    <h1>Page 1</h1>
  </section>

  <section id="page2" class="page">
    <h1>Page 2</h1>
  </section>

  <section id="page3" class="page">
    <h1>Page 3</h1>
  </section>

  <section id="page4" class="page">
    <h1>Page 4</h1>
  </section>

  <section id="page5" class="page">

  </section>
</div>

​Can you help me?

Set the data-spy="scroll" on the body tag and it should work. Please check the updated jsFiddle.
