Div Layering issue

[jet71dl]

1) Script Title: DD Tab Menu (5 styles)

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex1/ddtabmenu.htm

3) Describe problem:

I have two divs with one stacked on top of the other, both have links but the div on top blocks the other divs links.

How can I make it where both links will work, here is a link to an example:
EXAMPLE

You'll notice that the links labeled BUTTONS are not clickable because the div for the drop downs for the links above overlaps it...

Thank you for any help!
