thanks Jason, got further now but still not quite there.
I now get an error
'We cannot process this transaction because there is a problem with the PayPal email address supplied by the seller. Please contact the seller to resolve the problem. If this payment is for an eBay listing, you can contact the seller via the "Ask Seller a Question" link on the listing page. When you have the correct email address, payment can be made at www.paypal.com.'
I am using the primary email address for the paypal account and have tried the email addresses used to login to paypal, neither work and give the error above.
Could you help further please,
New files attached.
