title: select value from dropdown menu
body: <p>I want to make this source code, I copy this source code in my notepad and I paste it in one file, include CSS, JavaScript and HTML. The file name is <em>sel.php</em>.</p>
  
  <p>I take the source code from <a href="http://jsfiddle.net/davidThomas/x5YW3/" rel="nofollow">http://jsfiddle.net/davidThomas/x5YW3/</a></p>
  
  <p>I include my CSS with:</p>
  
  <pre><code>&lt;style type="text/css"&gt;
  ----this_source_css----
  &lt;/style&gt;
  </code></pre>
  
  <p>JavaScript with :</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  ----this_source_javascript----
  &lt;/script&gt;
  </code></pre>
  
  <p>And HTML in:</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
  ----html_source_code----
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>But this code does not work in my copy paste, whereas I run in jsfiddle working fine, what might be wrong?</p>
