dependent drop-down not populating query

Hi Guys,

 

I am trying to create chained dependent drop-downs with the third and final drop-down displaying its results in an html table. This all works fine until the final drop-down, where the variables from the previous two is not passed and instead the option value from select #city is displayed in table. Can anyone suggest what is missing between paper_type.php and paper_customisation.php that is causing this issue?

 

Here is the index.php...

<?php require('config.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" >

<script type="text/javascript" src="http://ajax.googleapis.com/
ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{

$(".product_select").change(function()
{
var dataString = 'id='+ $(this).val();
$.ajax
({
type: "POST",
url: "paper_type.php",
data: dataString,
cache: false,
success: function(html)
{
$(".paper_type").html(html);
}
});

});

$('.paper_type').live("change",function(){
var dataString = 'id='+ $(this).val();
$.ajax
({
type: "POST",
url: "paper_customisation.php",
data: dataString,
cache: false,
success: function(html)
{
$(".paper_customisation").html(html);
}
});

});



});
</script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
	$('#city').change(function(){
		city_id  = $('#city').val();
		$.post('paper_customisation.php',{city:city_id},function(res){
			$("#result").html(res);
		});

	});
});
</script>
<style type="text/css">
body {
	font-family: Arial, Helvetica, sans-serif;
	font-size: 12px;
	color: #333;
	background-color: #FFF;
	margin: 0px;
}
#frame1 {
	background-color: #F7F7F7;
	margin: 30px auto auto;
	padding: 10px;
	width: 700px;
}
#frame1 label {
	width:60px;
	display: inline-block;
	text-align:right;
	padding-right:10px;
}
</style>
</head>
<body>
<div id="frame1">
  <label>Product</label>
  <select name="product_select" class="product_select">
    <option selected="selected">--Select Product--</option>
    <?php
$sql=mysql_query("select * from product_id_name order by id ASC");
while($row=mysql_fetch_array($sql))
{
echo '<option value="'.$row['id'].'">'.$row['ProductName'].'</option>';
 } ?>
  </select>
  <label>Paper Type</label>
  <select name="paper_type" class="paper_type">
    <option selected="selected">--Select Paper Type--</option>
  </select>
  <label>Flat or Fold</label>
<select name="city" id="city">
   <option selected="selected">--Select Finish Type--</option>
	<option value="1">Flat</option>
	<option value="2">Fold</option>
	<option value="3">Creased & Fold</option>
	<option value="4">Creased & Flat</option>
</select>
<div id="result">
</div></div>
</body>
</html>

And here is paper_type.php...

<?php
require('config.php');

if($_POST['id'])
{
$id=$_POST['id'];
$sql=mysql_query("select * from paper_type where print_products_id='$id' ");
echo '<option selected="selected">--Select Paper Type--</option>';
while($row=mysql_fetch_array($sql))
{
echo '<option value="'.$row['id'].'">'.$row['PaperType'].'</option>';
}
}

?>

Here is the final chained drop-down...

<?php

$id = $_POST['city'];
require('config.php');

//find the record
$sql 		= " select * from northern_prices where finish_type = '".$id."' ";
$query 		= mysql_query($sql);

//fetch the results and display in a html table
	echo "<table border='1'><tr><th>ID</th><th>Name</th><th>City</th></tr>";
while( $row	= mysql_fetch_assoc( $query ) ){
	echo "<tr><td>$row[id]</td><td>$row[ProductQuantity]</td><td>$row[SingleSided]</td>";
}
	echo "</table>";
?>

I realise mysql_ is deprecated, but if I can only get the script to work I will endeavour to change that :) Thank you for any help.
