write code for added shipping charge when product is....

Hi all, I have window covering company and offer custom sized blinds and window coverings. In general I offer free shipping. However, I need additional code that will add a "flat shipping surcharge of 60$" when a product is "oversized". This means when the product is WIDER that 96". (The length is not of importance). I have attached an order page in html code that shows how my web order form looks like. This is the form that will have to be adjusted. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
