The validation URL does not validate!

Dear w3c,

We validated our site through the css and XHTML validator. Both  
passed so we added the url checker links to our page. And then when  
we retest it fails XHTML on the css validator link:

http://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F% 
2Fwww.northgate.litchfieldmorris.co.uk% 
2F&profile=css21&usermedium=all&warning=1

The url provided does not have correctly formatted ampersand! Please fix

Best Regards
Lee Tempest
