Using MC Tween

Im trying to make a movie clip gotoandStop at a specific frame but have no luck in succeeding…can someone help.

onClipEvent (load) {
this._alpha = 0;
this.alphaTo (100, 3.5, “easeOutCubic”,1);
this.onRelease = function() {
_parent.gotoAndStop(“square”);}
}

Is there something wrong with the code.
