Good evening (well it was until I started trying to get my wpp Paypal a/c working!)
If anyone can help me I'd be very grateful.
I have installed the WPP add on to my site:- www.skyproducts.co.uk.
I thought that i'd copied the code accross etc accurately but each time I try and make a test purchase, i get the following:-
An error occured when we tried to contact PayPal's servers.
Transaction refused because of an invalid argument. See additional error messages for details. (10401)
Order total is invalid.
I'm not a programmer and am trying my hardest to try and work through this meethodically but can't fathom out what is going on.
Thanks
