textcart - Purchasing error

Could you try remote the & in specified line :

Change

    $textcart_mgr->tab_display('', &$_SESSION['PO'], "display_order_in_tab");

to

    $textcart_mgr->tab_display('', $_SESSION['PO'], "display_order_in_tab");

/Elax

The textcart extension uses the "&$_SESSION" term in quite a few places - do they all have to be changed?
