Hmmm. You are using the latest ecommerce from Jedatech?

I get a similar error when I undo his changes in the OrderForm class. Around line 200 in the processOrder function should read:

    // Save payment data from form and process payment
    $form->saveInto($payment);
    $payment->OrderID = $order->ID;
    $payment->Amount->Amount = $order->Total();
    $payment->Amount->Currency = Order::Currency();
    $payment->write();

This handles the changes made in the Payment module to implement the Money class.

Hope this is of some help. Otherwise, do you have a stack trace?

yes...same position
