I'm trying to implement a jqModal on the home page here:

Scroll down and click on "Symptom Search"

The modal works well in Firefox, and Safari, but in IE7, I get the modal slapped behind the dropdown elements, and I can't click on the modal itself.

I've played around with z-index issues for about an hour now, and still haven't come up with a solution.

Anyone know what I'm missing here? I've been racking my brain for too long and it's slowly turning to mush.
