Answer 1

The code you provided works fine so the error you are seeing must have something to do with other code on the page. Most likely reasons are

1. You are missing references to the Bootstrap JavaScript or CSS files.
2. You are missing jQuery.
3. You have not put jQuery before the Bootstrap JavaScript reference.
4. There is another JavaScript error on the page, look in your browsers console for errors.

Example of your code working:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>

<nav class="navbar navbar-inverse navbar-fixed-top">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">Connor Clarke</a>
    </div>
    <div id="navbar" class="collapse navbar-collapse">
      <ul class="nav navbar-nav">
        <li><a href="../index.html">Home</a></li>
        <li class="active"><a href="#">Games</a></li>
        <li><a href="#contact">About</a></li>
      </ul>
    </div><!--/.nav-collapse -->
  </div>
</nav>
