On mouseDown problem

hello all!,
i have a main movie clip with this code:

onClipEvent (enterFrame) {
    this.onRollOver = function() {
        gotoAndPlay("Over");
        _root.BTN_Over_Sound.start();
    };
    this.onRollOut = function() {
        gotoAndPlay("Out");
    };
    this.onPress = function() {
        _root.BTN_Click_Sound.start();
    };
}

inside that mc i have 9 buttons they are also movie clips with the following code:

onClipEvent (load) {
    var pressed = !true;
}
onClipEvent (enterFrame) {
    var Mousex = _root._xmouse;
    var Mousey = _root._ymouse;
    if (this.hitTest(Mousex, Mousey) && pressed == !true) {
        _root.BTN_Over_Sound.start();
        pressed = true;
    }
    if (!this.hitTest(Mousex, Mousey) && pressed == true) {
        pressed = !true;
    }
}
on (release) {
    getURL("http://www.google.com");
}

and for somr reason the getURL part is not working…:diss:
i’ve tried to do it with a function but when using a function all the buttons
are being activated instead of just the one i clicked
im using flash 8 maybe someone could help out here?
thanks a lot for looking guys…:nerd:
