Just joined and a first article

Well this is just a little post to say I've just joined the community. I'm a Scottish based web developer working in the recruitment sector (which sounds really serious... scary). I tend to do a lot of Perl coding and have also recently got right back into Javascript having fallen out with it seriously in the 90's.

Anyway recently I needed to be able to have a form where a group of checkboxes had to interact with a group of radio buttons as if they were part of the set... So if a radio button was selected the checkboxes would all be cleared and if a checkbox was ticked the radio buttons would be cleared. After twiddling about with that for a while I tought people might find my result useful so posted it on my site.

Checkboxes that act like radio buttons

Any comments, critiques or questions are gratefully apprieciated.
