Problems with AS i think...?

Hi peeps
Could someone please take a look at my actionscript. Im having trouble loading another movie into an empty MC.

 
_root.menu.home_btn.onRelease = function() {
if (_root.currMovie == undefined) {
_root.currMovie = "home";
_root.empty.loadMovie("home.swf");
} else if (_root.currMovie != "home") {
if (_root.empty._currentframe>=empty.midframe) {
_root.currMovie = "home";
_root.empty.play();
}
}
};
_root.menu.private_btn.onRelease = function() {
if (_root.currMovie == undefined) {
_root.currMovie = "private";
_root.empty.loadMovie("private.swf");
} else if (_root.currMovie != "private") {
if (_root.empty._currentframe>=empty.midframe) {
_root.currMovie = "private";
_root.empty.play();
}
}
};

This is fine as i have used this script before on a prevoius website i have made. Its just doesnt want to work today! :frowning:

The problems seems to be it loads a movie in and can load a movie out but struggles to load the next movie … im i making sense?

I will post a link to my fla here, aleways makethings alittle clearer!
Thanks for any feedback in advance
