Ease, then alpha and then fade in new movie

1

Okay so im tryíng to do the following.

  1. Ease the topcontent down.
  2. Fade it out and at the same time fade/load in an new top.swf.content.
    How do i call this function with an button call? This is what i have now… Right now it does all this at the same time with no delay. So easing and alpha happens at the same time… Help me plz!!

//Easing… and setting alpha to zero…
function easeTo(tar) {
toppaper.onEnterFrame = function() {
this._yscale = tar-(tar-this._yscale)/1.2;
menuMc._y = this._y+this._height+1;
if (Math.abs(tar-this._yscale)<1) {
this._yscale = tar;
menuMc._y = this._y+this._height-1;
delete this.onEnterFrame;
}
this._alpha = 0-(0-this._alpha)/1.2;
if(Math.abs(this._alpha-0)<1){
this._alpha = 0;
delete this.onEnterFrame;
}
}
}
