This program will only work if you have a browser that is JavaScript enabled. If you are on this page, your browser is not up to the task. There are two possible solutions. Your browser might have JavaScript disabled (Check under "Options.") If your browser is earlier than Netscape 3.0, then you need to download a later version of Netscape. This will also work (although not quite as well) with Microsoft's Internet Explorer, version 2.0 or later.
All of the student labs on campus have up to date browsers.
