Button of MC?

programming flash
1

the first part only works on a MC, and the bottom part only works on a button? Why won’t they both work on just a MC?

Thanks

on (release) {
_root.changePhoto(“0”);
}
on (release) {
loadText = new loadVars();
loadText.load(“data.txt”);
loadText.onLoad = function(success) {
if (success) {
name.html = true;
name.htmlText = this.name;
}
};
}
