Site Broken in IE - Can you point me in the right direction?

I’m sort of fixing a website that was originally developed by another person. It’s sort of a quick job, last minute kind of thing. Sort of doing it as a favor. I’ve not gone through it’s CSS too thoroughly and am currently working on a Mac since my PC broke down (so I don’t have easy access to IE).

Can someone point me in the right direction with this IE issue?

It’s apparently broken in Internet Explorer 6,7 and 8. I feel a bit unarmed at this task.

It would not be broken in IE 8 if it were not invalid.

Currently it is putting IE into quirks mode, you do not want that.

ah, silly mistake. thanks.
