Hi I have a test site set up with Dynamic Price Updater and the attributes are going crazy.

Using http://sitstandforbusiness.com/ssfbt...desk-p-50.html as an example.the price is £224.17 based on the standard or bespoke desktop. The frame only option is meant to discount the price, (which it does) but when you visit http://sitstandforbusiness.com/ssfbt...desk-p-50.html

When I disable VAT it all works fine, but when its included (20%) everything just plays up.

Please could anyone advise? Any advice would be welcome
