title: Set the value for a hidden parameter from the URL using javascript
body: <p>I'm trying to set the hidden field for 'item_number' from the Url QueryString for a paypal form.</p>
  
  <p>So the URL will look like this "http://website.com/customize.aspx?item_number=FFFF"</p>
  
  <p>and code:</p>
  
  <pre><code>&lt;script language="javascript" type="text/javascript"&gt;
  document.getElementById('item_number').Value = Request.QueryString('item_number');
  &lt;/script&gt;
  
  &lt;input type="hidden" name="item_number" value=""&gt;
  </code></pre>
  
  <p>But this doesnt work for me. Whats wrong here???? is there a better way?</p>
