I have added two fields to my customers table: customers_account_name & customers_account_number

I want to add these as $_SESSION variables at login, so I edited /includes/modules/pages/login/header.php and added the following code:

about line 47: get customer info
Code:
    // Check if email exists
    $check_customer_query = "SELECT customers_id, customers_firstname, customers_lastname, customers_password,
                                    customers_email_address, customers_default_address_id,
                                    customers_authorization, customers_referral, 
			  	    customers_account_number, customers_account_name
                           FROM " . TABLE_CUSTOMERS . "
                           WHERE customers_email_address = :emailAddress";
about line 84: create session variables
Code:
        $_SESSION['customer_id']                 = $check_customer->fields['customers_id'];
        $_SESSION['customer_default_address_id'] = $check_customer->fields['customers_default_address_id'];
        $_SESSION['customers_authorization']     = $check_customer->fields['customers_authorization'];
        $_SESSION['customer_first_name']         = $check_customer->fields['customers_firstname'];
        $_SESSION['customer_last_name']          = $check_customer->fields['customers_lastname'];
        $_SESSION['customer_country_id']         = $check_country->fields['entry_country_id'];
        $_SESSION['customer_zone_id']            = $check_country->fields['entry_zone_id'];
        // added fields
	$_SESSION['customers_account_number']    = $check_customer->fields['customers_account_number'];
	$_SESSION['customers_account_name']      = $check_customer->fields['customers_account_name'];
This DOES create the $_SESSION[] variables, but they are empty. It looks straight forward, so I don't know what I'm missing.

I can echo any of the other $_SESSION variable and get the expected value, so I don't know why these two are blank when the values are entered correctly in the customers table...????

Would really appreciate any help getting this right!

Thanks,
