    I have this error when trying pay. 


    Transaction refused because of an invalid argument. See additional error messages for details.
    The totals of the cart item amounts do not match order amounts.

    I see you are using the PayPal Express integration. It requires an API username, password and signature.


    Maybe this is not what you want? Most people use the standard PayPal integration that requires only your email address for the PayPal account you signed up with.
