If you dont mind, I have further question.
I have added an item to the products table for wholesale price (ProductWPrice). The idea is a 'wholesaler' logs in with a email, password and customer number. I have set this up and created a rule - memberlogeddIn. What I was planning was if this rule is passed, the products (& detail) pages will display the wholesale price(ProductWPrice) instead of ProductPrice.
I am not sure how to fit this around the Bottom Price code.
