[login to view URL] (will not work in IE) Need someone to do following: Have admin panel but all products are added with delivery and collection options, need modified so option not to have delivery and collection for certain products. Already have an option to disallow certain date ranges being booked, need modified so I can have multiple date ranges disallowed. If function is within x weeks (x set from admin) then full amount is due, currently they only pay booking fee. Have form to add and edit orders in backend but need modified so it makes use of product options.
