Objects and Session Problem

[fnbcprog]

Basically what i am trying to do here is have a user enter a classified in my form and post it to the website. If the user does not have a current login then i want to store the form data in an object of storeAuto class. After the user logs in I want to call the post function which is a method of the storeAuto class to post the object's variables.

I cant print or access any of the variables stored in $_SESSION['storeAuto'].

I am trying to echo it out by: $_SESSION['storeAuto']->year

But that wont work at all

I hope you can help

include_once($_SERVER['DOCUMENT_ROOT'] . "Zebrick/bin/globalOP.php");

	$cents = strip_tags($_POST['cents']);
	$price = $dollars . "." . $cents;
	$email = trim(strip_tags($_POST['email']));

By the way this is the class file

*/
class storeAuto {
	var $year;
	var $manufactr;
	var $model;
	var $style;
	var $description;
	var $price;
	var $email;
	var $zip;

// Contructor Function
function storeAuto($year,$manufactr,$model,$style,$description,$price,$email,$zip) {
	// Object's year attribute is set to passed variable
	$this -> id_user = $id_user;
	$this -> year = $year;
	$this -> manufactr = $manfactr;
	$this -> model = $model;
	$this -> style = $style;
	$this -> description = $description;
	$this -> price = $price;
	$this -> email = $email;
	$this -> zip = $zip;
}

function postAttributes() {
	// Establish a connection if not present
	require($_SERVER['DOCUMENT_ROOT'] . "Zebrick/bin/globalOP.php" );
	require_once($PATH_TO_CONN);

	// Insert into table
