Проблема со скриптом рейтинга PHP & MySQL?

Я нашел этот script на about.com, о котором я пытаюсь узнать, о том, как создать рейтинговую систему, но script по какой-то причине не будет считать голосование при нажатии ссылки и отправит меня страница, которая не найдена. Страница должна просто перезагрузить себя и подсчитать голоs >

Мне было интересно, как я могу исправить эту проблему? И какую часть кода мне нужно изменить и где?

Ниже показано, как выглядит страница, которую я тоже отправил.

<?php
// Connects to your Database
mysql_connect("localhost", "root", "", "sitename") or die(mysql_error());
mysql_select_db("sitename") or die(mysql_error());



//We only run this code if the user has just clicked a voting link
if ( $mode=="vote")
{

//If the user has already voted on the particular thing, we do not allow them to vote again $cookie = "Mysite$id";
if(isset($_COOKIE[$cookie]))
{
echo "Sorry You have already ranked that site <p>";
}

//Otherwise, we set a cooking telling us they have now voted
else
{
$month = 2592000 + time();
setcookie(Mysite.$id, Voted, $month);

//Then we update the voting information by adding 1 to the total votes and adding their vote (1,2,3,etc) to the total rating
mysql_query ("UPDATE vote SET total = total+$voted, votes = votes+1 WHERE id = $id");
echo "Your vote has been cast <p>";
}
} 



//Puts SQL Data into an array
$data = mysql_query("SELECT * FROM vote") or die(mysql_error());

//Now we loop through all the data
while($ratings = mysql_fetch_array( $data ))
{

//This outputs the sites name
echo "Name: " .$ratings['name']."<br>";

//This calculates the sites ranking and then outputs it - rounded to 1 decimal
if($ratings['total'] > 0 && $ratings['votes'] > 0) {
    $current = $ratings['total'] / $ratings['votes'];
}
else{
     $current = 0;
}
echo "Current Rating: " . round($current, 1) . "<br>";

//This creates 5 links to vote a 1, 2, 3, 4, or 5 rating for each particular item
echo "Rank Me: ";
