Having the same problem, I think, but in UK where payment using credit card (buyer without a paypal account) is taken through US identity questions like US State and not UK County also US Zip Code and not UK Post Code. I am sure this must be a language thing again. I can edit the os_paypal.php file to alter the US in the setParam lines, as per previous Italian post, but what is the right code? UK maybe or GB maybe?
Quick help would be appreciated
Thanks Jonathan
