Thanks for the info, Jason. I figured there must be a good way to add groups - your pre-built solutions are very good. But I didn't see how.
My browser is FF 5.0 but it's displaying the page fine today. I tried several times yesterday but it occurred to me this morning that I maybe should have tried clearing my cache yesterday. That can often solve a multitude of strange issues and I should have thought of it.
Thanks for the info again.
