Just FYI: I tested in NS6.2 and the page does not function. In looking at your source, I note that you have forks using n = (document.layers) ? 1:0 ie = (document.all) ? 1:0 as the tests. NS6+ doesn't recognize either of these proprietary DOM methods. It only recognizes W3C standards, such as document.GetElementById. Thus, it returns no to both tests and doesn't try to run either fork. I don't know what your proficiency is with javascript and DHTML, but if you are unsure how to add compatibilty for W3C compliant browsers (that includes IE6 (mostly anyway) and Opera, not just NS6/Mozilla), I suggest you explore dhtmlshock.com and dynamicdrive.com for similar cross browser effects for clues on how to adapt your existing code. You may even find one that you like better...both sites have some excellent "cut and paste" scripts available.
