preloader doesnt work

[deniel87]

this script doesnt work, why?

onClipEvent (enterFrame) {
        loadedbytes = _root.getBytesLoaded();
        totalbytes = _root.getBytesTotal();
        if (totalbytes == loadedbytes) {
                _root.nextScene();
        }
}

It is placed in a MC, inside a MC, in the first frame of the first scene. The frame has a stop action.
Im pretty sure everything works except the "_root.nextScene" because I tried replacing it with another action and it worked.

onClipEvent (enterFrame) {
    loadedbytes = _root.getBytesLoaded();
    totalbytes = _root.getBytesTotal();
    if (totalbytes == loadedbytes) {
        setProperty(_root.MC1, _alpha, 50);
    }
}

hey, I tried this:

onClipEvent (enterFrame) {
    loadedbytes = getBytesLoaded();
    totalbytes = getBytesTotal();
    porc = 100/totalbytes*loadedbytes;
    if (porc == 100) {
        _root.gotoAndPlay(2);
    }
}

AND IT WORKED!!!
I thought it would do nothing, bacause the scene has only one frame... but it went and played the next scene!
Now Id like (if it is possible) to understand what happened
