Dynamic Alpha

programming flash

I’m using this code to move things around on the stage

onClipEvent (load) {
	easeMove = function (xpos, ypos) {
		_x += (xpos-_x)/7;
		_y += (ypos-_y)/7;
	};

So I thought if I modified my code to work with an alpha that would be cool.

onClipEvent (load) {
	easeFade = function (fadeUp, fadeDown) {
		_alpha += (fadeUp-_alpha)/7;
                _alpha += (fadeDown-_alpha)/7;
	};

button triggers

	services.onEnterFrame = function() {
		this.easeMove(62, 10);
	    this.easeFade(50,0)
	};

What is it I’m missing?
