Adding size variable to paypal ipn

I’m just trying to add a size variable to the IPN so when the client receives the order information, they can view what size was requested, so far I’ve added this to my button:

[code=php]<input type=”hidden” name=”on0″ value=”CustomID”>
<input type=”hidden” name=”os0″ value=”echo $size[size]”>[/code]

and this to the IPN

[code=php]$customid = $_POST[‘option_selection1’];[/code]

as well as updating the database INSERT, can anyone see any reason why this wouldn’t work properly as I’m having trouble with it, here is the cart page

[code=php]<?php
session_start(); // Start session first thing in script
// Script Error Reporting
error_reporting(E_ALL);
ini_set(‘display_errors’, ‘1’);
?>
<?php

if (isset($_POST[‘pid’])) {
$pid = $_POST[‘pid’];
$size = $_POST[‘size’];
$wasFound = false;
$i = 0;
// If the cart session variable is not set or cart array is empty
if (!isset($_SESSION[“cart_array”]) || count($_SESSION[“cart_array”]) < 1) {
// RUN IF THE CART IS EMPTY OR NOT SET
$_SESSION[“cart_array”] = array(1 => array(“item_id” => $pid, “size” => $size, “quantity” => 1));
} else {
// RUN IF THE CART HAS AT LEAST ONE ITEM IN IT
foreach ($_SESSION[“cart_array”] as $each_item) {
$i++;
while (list($key, $value) = each($each_item)) {

if ($key == “item_id” && $value == $pid){
if ($each_item[‘size’] == $size){

// That item is in cart already so let’s adjust its quantity using array_splice()
array_splice($_SESSION[“cart_array”], $i-1, 1, array(array(“item_id” => $pid, “size” => $size, “quantity” => $each_item[‘quantity’] + 1)));
$wasFound = true;
}} // close if condition
} // close while loop
} // close foreach loop

if ($wasFound == false) {
array_push($_SESSION[“cart_array”], array(“item_id” => $pid,”size” => $size, “quantity” => 1));
}
}
header(“location: cart.php”);
exit();
}
?>
<?php

unset($_SESSION[“cart_array”]);
unset($_SESSION[“tradesrgr”]); //unset all sessions if cart is empty
unset($_SESSION[‘amount’]); //unset all sessions if cart is empty

}

} // close if condition

}
}
?>
<?php
