I'm having a lot of trouble with what seems should be straightforwards. The shipping costs aren't showing on the checkout or the receipt.
in my confif.php file I have
SimpleShippingModifier::set_charges_for_countries(array('ca' => 10));
i've looked at the orderinformation_editable.ss template and can see the <% control Modifiers %> where it looks for modifiers but for some reason simpleshippingmodifier is not being noticed. Has anyone else had this problem?
