Thanks for everyone's help - it's great to know that there are people who 
care about other's successes, and are willing to help at every stage.

I found that the "Rowspan" parameter was just what I was looking for, and 
it works great. I'm sure that the nesting tables idea will work, but as it 
won't work as well in Netscape, it's not ideal.

Anyway, thanks to everyone, and good luck with any projects you may be 
involved in!
