Problem with Shipping Estimator

[Nick1973]

Hi, I have a problem with the shipping estimator.

When I put in a place and country on the website e.g. France, Paris it just goes to a blank page when not logged in. If logged in its able to calculate the shipping from the account address, however if not it doesn't calculate anything.

The website URL is www.dottybettys.com

Does anybody have any answers?

Thanks

Nick

Just thought I'd add that if in the UK it calulates the shipping at the bottom of the page but won't calculate when changing country.
