Thanks for the feedback from frustrated customers who let me know about the paypal order link (for spain) not working correctly. This has now been rectified thanks.
Also we have now configured the system to connect to our UK account which automatically shows Paypal in English so that you can now understand whats going on! There is a link at the top right to choose Spanish or French.
Thanks again to the guys down in St Javier who persevered with this :)
