Bugfixing to modified oscommerce webshop - repost

Some changes are needed on this site: [login to view URL] -When clicking on a product in this category, there's a redirect loop. [login to view URL] -When clicking on the product HU506326302 in the category [login to view URL] , there's also a redirect loop. This product belongs to another group (see url on the product) but is displayed in 2 groups (on purpose). This might explain the redirect problem, but should be fixed. -Remove regular expressions and mask in the create_account page for the fields: phonenumber Need this fixed asap.
