ActionScript 2.0 :: Creating Save File Using SharedObject?

I have attempted to create a save file using sharedObject but it doesn't work. I don't get any errors it just doesn't seem to save when I press the save button. In the main frame I have:

Code:
user_so = SharedObject.getLocal("user");
if(user_so.data.tclock != undefined) {
clock_txt.text = user_so.data.tclock;
gregism_txt.text = user_so.data.gregism;
} else {
gregism = 0
clock = -1
}

In the save button movie clip I have:
Code:
on(release) {
user_so.data.tclock = _root.clock_txt.text;
user_so.data.gregism = _root.gregism_txt.text;
user_so.flush()
}
