Text easing in without mouse clicking!

looked at the tutorial in for text easing on mouse click i took out the mouse click funcion. now what do i do now? need some understanding. I take out the mouseclick function

onClipEvent (load) {
	_x = 600.4;
	_y = 535.4;
	speed = 5;
}
onClipEvent (enterFrame) {
	_x += (endX-_x)/speed;
	_y += (endY-_y)/speed;
}

now it starts out aht onClipEvent(load)
but it ends up in 0.0 / 0.0

I dont understand how i would change the OnClipEvent (enterFrame) code to make it move where i want to go.
