Flashfader plugin help

Please help!

I need my flashfader to go behind my page menu. I have played around with the code in my header.php but can’t figure it out!

I have my flashfader on my site where I want it but it hides the sub levels of my page menu. =[

Here is my site currently: http://www.customweddingdetails.com/blog/

How can I make the flashfader show up BEHIND my sub level menus instead of IN FRONT Of?!!!!

Please help!
