hi everyone, fairly new to php and i am trying to complete a shopping basket on my site. I have got it working locally but as soon as i upload it to the remote version it stops working.

here is the error i get:

Warning: Cannot use a scalar value as an array in /home/nas03l/d/mysite.co.uk/user/htdocs/basket.php on line 24

Warning: Cannot use a scalar value as an array in /home/nas03l/d/mysite.co.uk/user/htdocs/basket.php on line 24

Warning: Cannot modify header information - headers already sent by (output started at /home/nas03l/d/mysite.co.uk/user/htdocs/basket.php:24) in /home/nas03l/d/mysite.co.uk/user/htdocs/basket.php on line 26

and here is the code for the basket page ( i have removed some of irrelevant code):

Code:
<?php
session_start();
if (!isset($_SESSION['cart']))
{
	$_SESSION['cart'] = array();
}
if (!isset($_SESSION['addon']))
{
	$_SESSION['addon'] = array();
}
if (isset($_POST['bid']))
{
	$_SESSION['cart'][] = $_POST['bid'];
	if (isset($_POST['addon']))
	{
	$addonarrays = $_POST['addon'];
	}
	else
	{
	$addonarrays = array();
	}
	
	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();
}
?>

</body>

and here is the code for form that submits:

Code:
<table width="98%">
			
	
				 <tr>
				 <?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 "<td align='center'><label>$addonname</label><input type='checkbox' name='addon[]' value='$addonid'></td>\n";
						
					}
				 ?> 
				 </tr>
				 
				 <tr>
				 <?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='pictures/$addonrefnum.jpg'></td>\n";
					}
				 ?> 
				</tr>
				<input type="hidden" name="bid" value="<?php echo "$id" ;?>" />						
			</form>
			</table>
