Flash site on top of random background

hey folks

I’ve followed the tutorial on loading of a random background. My question is :

How do i go about creating the site on top of the background. If i start building up the site in the same swf as the one that holds the random background scripts, how do i get the menus to load after the background has been shown. ? Im basically uncertain on the hole structure on the site.
I’ve followed the tutorial on creating a full flash site, but here the background is just a layer underneath the menus.

thx
