Embedded dropdown menu not working

so heres the deal i have a drop down menu that for some reason is not picking up button presses, im starting to think its because the drop down menu is within another movie clip, but its driving me nuts, any reasons why an embeded movie clip wouldnt be picking up a hitTest or a this.onRelease ??? ahh driving me nuts heres my code im using the undocumented tween class :crazy: :crazy: :crazy:

onClipEvent(load){
//portfolio dropdown
this.onRelease = function() {
easeType = mx.transitions.easing.Regular.easeInOut;
var begin = _root.portfoliolink_mc.portwebdev_mc._y;
var end = 300;
var time = .5;
var mc = _root.portfoliolink_mc.portwebdev_mc;
ballTween = new mx.transitions.Tween(mc, “_y”, easeType, begin, end, time, true);
this.gotoAndPlay(2);
}

this.onRollOut = function() {
easeType = mx.transitions.easing.Regular.easeInOut;
var begin = 300;
var end = 35;
var time = .5;
var mc = _root.portfoliolink_mc.portwebdev_mc;
easeback = new mx.transitions.Tween(mc, “_y”, easeType, begin, end, time, true);
this.gotoAndStop(1);
}
}
