Thanks Jonathan.
Trust me, I have tried many combinations, including the one you suggest, but it doesn't work.
I am afraid it is a bit more complicated ...

What I am trying to do is this. When you enter a letter in the form, you get some suggestions for categories that start with that letter. I just need the links to work. And for someone to develop a script that Opera likes, but as long as it works in firefox and msie, I'm happy.

I guess this might be useful for adding links too, but am not sure how that would work.
