Browser Compatibility Problem

I have a project that was previously completed by a coder with specs of: --------------------------------- | **Description: Have an html web page that contains a form with a drop down box and a submit button. Form is like <form name="testform" method=post action="**[**http://www.**][1]**[login to view URL]"> Submit button is <input type=submit name=add value="Add to Cart"> and there are several hidden input values including the value from the drop down box. My Objective. ONLY When customer makes a selection of the dropdown box they should get a pop-up window or menu box that can have a small paragraph of information and command buttons that should say something like "This is a gift" and "This is for personal use". If the person selects "this is for personal use" I want the value of the drop down control to change to the default value which is "novalue" and then the page should continue on to the form post action page. If "This is a gift" is selected then no change to values and the page controls continues to the form post action page. If the drop down box was never changed then this window should never come up. ----------------------------------------- **The code for this was completed and is working fine in IE but is not working in Netscape - I need this to work in both! The code is using Javascript to create a Dialog window that makes the selection and then alters the input value based on the selection. I will provide the current code to the selected bidder - you may use or discard - as long as the objectives are met. | ## 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.
