Lightbox pop up image shows underneath content

[peppermintcake]

Hello,

I have a lightbox of images and a youtube video player together on the same page. When you click on the image thumb nail in IE 9 and IE8 the popup shows directly underneath the video player.

In Firefox, the popup shows on top of the video player but if you click on one of the bottom thumbnails you will see that the "close button" of the popup is cut off.

I would like to have the popup image overlay ontop of the video.

Here is the link to the page: http://tilsonpr.com/news.asp

What am I missing here? Thanks for the help
