Shipping Exception Notice

May be a wishlish…but not sure

CS-Cart v2.06

Want to be very clear on International orders policy. So I’ve added a sidebox/page…but looking for a way to confirm.

I want to add an additional required checkbox in the checkout ONLY for International customers. (under terms)

so I added the the checkbox in the template file, but not sure what code I need to add to only show for customers outside my base region.

Can anyone with a bit more cs-cart experience help?

OR Is there a better way to do this?
