just a quick general question to get me started .
the products are coming from the u.k so i changed the contry and zip in the shipping/packaging section then in moduals i added ups .
its up on my site but comes up with

United Parcel Service
We are unable to obtain a rate quote for UPS shipping.
Please contact the store if no other alternative is shown.

any ideas where to start .
any information pointing me in the correct direction will be a big help
