Banjer,

Thanks, I've saved html thread and I'll study it in detail off line. I have to admit I kept seeing the thread title and shying away from it - too hard basket, but maybe I'll learn it bit by bit as I need it.

John, Both of those links took me elsewhere but both said that the page didn't exist. I think the site addresses might be wrong or something, but the important thing in this thread is that the clicky thingies actually did what they were supposed to do.
