Loading external SWF problem

[Sir Yendor]

I'm using this code on a button to load and external SWF in to empty movie clip.

on (release) {
_root.songs.loadMovie("july10music.swf");
gotoAndStop("day1");
}


where songs is the name of the empty movie clip.

It works fine on my computer but when I load everything to the server, all in the same directory, it doesn't work.

Any ideas?

Thanks
