Session works after first visit

[Mufleeh]

Hi All,

 

I have an issue with the session variable.

 

shoppingcart.php is the first file executed and contains the following code,

$postal_charges	            =	get_meter_square() * $postageRate;
$_SESSION['postalcharges']  =	$postal_charges;

and once the 'Proceed' button is pressed its re-directed to purchase.php as following,

window.location='purchase.php';

In purchase.php the value of $_SESSION['postalcharges'] doesn't read. But if I go back and click on 'Proceed' again it reads.

 

Moreover this happens only on Firefox latest one. Can anyone help me on this?
