Error message from ebay

I am new to garage sale, I have made a new template, I then went on verify template and I get the following message.
This listing does not meet the cross border trade requirements.
I don`t know what I have done wrong, but any help would be gratefully received.

Hi oggy,

this error/warning is returned and generated by the eBay system (not by GaragSale).

I guess you get this error message from eBay because you use international shipping options in your listing (and the “International Visibility” enhancement?).
If so it might help to list one auction with international shipping options through the eBay website once. eBay probably then shows you a link/address or gives you better instructions what to do.
