please help buttons not loading mc....?

hi all!

my index page is not loading the swf files from the buttons. can someone please take a look and assist me?

files (index, contact) are here

my index button script is:

b1.onRollOver = over;
b1.onRollOut = out;
b1.onRelease = home;

function over() {
this.gotoAndPlay(2);
}
function out() {
this.gotoAndPlay(16);
}
function home() {
_root.emptyMC.loadMovie("home.swf");
}

the emptyMC on my index page is instance named "emptyMC".

thanks so much. :)

Without looking at your files, mabey this might help. (line edited below)
_root.loadMovie("home.swf", "emptyMC");
