Getting flyouts to play nice with others

I have a rather tricky and interesting question.
I run the site and I’m trying to customize a template with a flyout menu.
The template in question is a modification of the fluid-based layout template LazyDays from The flyout is by Stu Nicholls and can be found here.

The problem I’m having is that the menu works fine in firefox, but when I open it in IE, it won’t flyout. The tricky and interesting part is that if I just use the menu outside of my template–as a standalone. It works fine in both FF and IE. There is something in my template that breaks the flyout. I would really appreciate if someone could take a look and see what’s what with the template. A copy of the template, with the flyout added, twice in two different ways, is located here.
Thank you for your time.
