Is the fault with the Jquery?

Hi Guys

I know nothing about javaScript, but im trying to ammend somebody else's script to work with mine, but its not working an i think it may be down to the JavaScript.

Would somebody mind taking a loook and see if they can spot an error?

Basicaly, it is a rating system with 3 files. The first file (gamecard.php) contains a link to the other two files...Either 'Up.php' or 'Down.php'. When a user clicks on one of the links, the number will should increase by one. However, at the minute, the number disapears and doesnt refresh or store in the db

The 3 peices of code are:

Gamecard.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Voting with jQuery, Ajax and PHP</title>
<script type="text/javascript" src="jquery.js"></script>

<script type="text/javascript">
$(function() {

$(".vote").click(function() 
{

var id = $(this).attr("id");
var name = $(this).attr("name");
var dataString = 'id='+ id ;
var parent = $(this);


if(name=='up')
{

$(this).fadeIn(200).html('<img src="dot.gif" align="absmiddle">');
$.ajax({
   type: "POST",
   url: "up_vote.php",
   data: dataString,
   cache: false,

   success: function(html)
   {
    parent.html(html);
  
  }  });
  
}
else
{

$(this).fadeIn(200).html('<img src="dot.gif" align="absmiddle">');
$.ajax({
   type: "POST",
   url: "down_vote.php",
   data: dataString,
   cache: false,

   success: function(html)
   {
       parent.html(html);
  }
   
});


}
  
  
   


return false;
});

});
</script>
</head>
<?php

{

}

$result=mysql_query("select down from Games where gameid='$id'");
$row=mysql_fetch_array($result);
$down_value=$row['down'];
echo $down_value;

}
?>

The error may very well be in the php but im not so sure. Your help will be appreciated

UPDATE: I have found that this works when i try to use it through the absolute path (www..../..../gamecards.php)

It is not working when i try to use it through www....../reviews.php which gamecards.php is an include of.

Does anybody have any idea why?

Thanks
