Tween on Rollover?

[jmh722]

Hi, I have a vertical tween using the tween class that I want enacted when a user rolls over a button. I attached the code below, because I am stuck.
Thanks in advance

function toggleMenuTween (obj) {
	var toggleTween:Tween = new Tween(obj, _y, Regular.easeIn, 337, 357, 2, true);
}

togglemenu.onRollOver = function() {
		this._alpha = 100;
		trace(this._name);
		toggleMenuTween(this);
}

togglemenu.onRollOut = function() {
	this._alpha = 0;
}

The second parameter of Tween() is a String.

new Tween(obj, "_y", ...);
