Reload a DIV without reloading the whole page

Reload a DIV without reloading the whole page

I have a Div Tag that has a php include to fill that div with information
what I want to do is make it so that the page is called every 15s so it
can update the information there without having to reload the whole
webpage. I've tried to do this with JavaScript/jQuery and I just can't
seem to get it to work
<script type="text/javascript"
src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js" />
<script type="text/javascript">
var auto_refresh = setInterval(
function ()
{
$('.View').load('Small.php').fadeIn("slow");
}, 15000); // refresh every 15000 milliseconds
</script>
<div class="View"><?php include 'Small.php'; ?></div>
this is what I have after searching some, and what happens is, it loads
the Small.php but it doesn't refresh it or update the info every 15
seconds.
please help!
I should add all my php arrays that should show up are all executed in the
Small.php and the page I'm including it into is just so it's isolated.
