Ive tried to do the setup again, its a problem with the CRYPT field they require all the info posting in, it seems that none of the fields are been recognised from it.
Get errors on all the following fields
amount
currency
vendorTXCode
description
etc etc
I also noticed that when running the checkout process it adds the link to protx test server not sagepay is this something that will be updated in the future.
