Basket not retaining array session.

Hi all, hope someone can help with this. It's driving me bonkers

I wondered if some body knows how to retain the session ($_SESSION['addon']) for my shopping basket, i lose it when i navigate to another page or refresh the page. The $_SESSION['cart'] is fine. Thanks in advance for your time and help!

This works on my local version just not on the remote ???

here is the header code:

<?php
session_start();
if (!isset($_SESSION['cart']))
{
	$_SESSION['cart'] = array();
}
if (!isset($_SESSION['addon']) || !is_array($_SESSION['addon']))
{
	$_SESSION['addon'] = array();
}

if (isset($_POST['bid']))
{
	$_SESSION['cart'][] = $_POST['bid'];
	
	$addonarrays = array();
	
	if (isset($_POST['addon']) && is_array($_POST['addon'])) 
	{
      $addonarrays = $_POST['addon'];
	}  
	
	foreach($addonarrays as $addonarray)
	{
	$_SESSION['addon'][] = $addonarray;
	}
	
header('location: ' . $_SERVER['PHP_SELF'] . '?' . SID);
exit();
}
if (isset($_GET['empty']))
{
	unset($_SESSION['cart']);
	unset($_SESSION['addon']);
header('location: ' . $_SERVER['PHP_SELF'] . '?' . SID);
exit();
}

Code (markup):

and here is the form that submits it

<form action="basket.php" method="post">
						
	
				 <?php 
					$addon = @mysql_query("SELECT DISTINCT id, refnum, name FROM addon, addonsubmenucat WHERE id=addonid AND catid=2 LIMIT 0, 4");
					while ($addons = mysql_fetch_array($addon))
					{
						$addonid = $addons['id'];
						$addonname = $addons['name'];
						$addonrefnum = $addons['refnum'];
						
						echo "<label>$addonname</label><input type='checkbox' name='addon[]' value='$addonid'>\n";
						
					}
				 ?> 
			
				 <?php 
					$addon = @mysql_query("SELECT DISTINCT id, refnum FROM addon, addonsubmenucat WHERE id=addonid AND catid=2 LIMIT 0, 4");
					while ($addons = mysql_fetch_array($addon))
					{
						$addonrefnum = $addons['refnum'];
						
						echo "<td align='center'><img src='thumbnailpictures/$addonrefnum.gif'>\n";
					}
				 ?> 
				
				<input type="hidden" name="bid" value="<?php echo "$id" ;?>" />
				<input type="submit" id="buybutton" value="Add to basket" />
