I used to know how to do this and my mind has gone mushy. I've gone through the forums but can't find my answer. Sorry if this is simple, just can't work it out.

Our shop is currently set up for billing and shipping addresses only to 1 country. But, we need to accept foreign credit cards so we want to allow multiple countries in the dropdown for billing address, but keep only 1 in the shipping address.

Can't figure it out -- and a customer is waiting to put through his order. Any help on this annoying problem?

Thanks!
