RSS Help

I've been asked to create an RSS feed but this is my first time using it and I'm stuck.

Let's say I use the W3Schools example as follows
<?xml version="1.0" encoding="ISO-8859-1" ?>
<rss version="2.0">

<channel>
  <title>W3Schools Home Page</title>
  <link>http://www.w3schools.com</link>;
  <description>Free web building tutorials</description>
  <item>
    <title>RSS Tutorial</title>
    <link>http://www.w3schools.com/rss</link>;
    <description>New RSS tutorial on W3Schools</description>
  </item>

    <title>XML Tutorial</title>
    <link>http://www.w3schools.com/xml</link>;
    <description>New XML tutorial on W3Schools</description>
  </item>
</channel>

</rss>

How comes when I link to it from my homepage instead of the subscribe bar popping up it says:

[code]
        This XML file does not appear to have any style information associated with it. The document tree is shown below.[code]

All help appreciated.

Works fine for me.
