Issue with EURO currency

I've a serious problem with the paypal checkout when EURO is selected as currency. Shortly, even if i don-t set any shipping price, on paypal page is showing a shipping cost that increases according with item quantity the customer selects.

Here is the script, as you can see i made the example really simple:

    simpleCart({

        cartStyle:"table",
        currency:"EUR",

            checkout: { 
                type: "PayPal", 
                email: "info@vintagebakery.it",
                        },

        });

I've uploaded also two examples, very basic, of what happen when you make checkout:

Link 1 test.htm : with Euro currency selected (and with shipping issue) http://www.vintagebakery.it/test/test.htm

Link 2 testuk.htm : any other currency (in this case GBP), and correctly no shipping added http://www.vintagebakery.it/test/testuk.htm

Feel free to check both link to see my problem. Does anyone has a solution for this tricky problem? I rely on you to complete my first shopping cart!!!

Thanks in advance Matteo
