Okay guys, got an interesting one for you:
I'm designing a site for my college band program. You can view it here:

http://www.wm.edu/CAS/music/band/new/

That's what I have so far.

What I need help with is this: for some of the links that will be in the bar on the left, I want the info to come up in the table on the right, without loading a new page. Does it make any sense to do it like that? I only say because the amount of info that will show up won't be worth a whole new page.

So what would I need for this to happen? All that the stuff there right now is tables. Nothing fancy.
