correct code to work with firefox

I have some code that allows buyers to select delivery options using radio buttons and a check box. The results of these sends a url via the [login to view URL] function to my card processor. In internet explorer this works well. As the [login to view URL] function does not work with the firefox browser I need the code to be rewritten so that it will work with both browsers. The code can be seen on this page [login to view URL] I require the changes to be done within 2 days. ## 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.
