Based on another forum, I started out using both div and iframes on my site. The idea was to use CSS more as the layout manager, and iframes more as the content manager.

I tested mainly in Safari, where it works flawlessly. In Firefox, however, I can't get the submenus "Why Join" or "Job Openings" to update the iframe.
I'm beginning to wonder whether I should have tried to do everything using div, but it looks like that would require javascript, which I'd rather not do.
Please tell me I'm simply missing something easy.
