Function and delay time


i have this as

function animaTexto(txt, pt) {

    attachMovie(txt, txt, this.getNextHighestDepth());
    this._x = (Stage.width/2);
    this._y = (Stage.height/2);
    this._alpha = 0;
    Tweener.addTween(this, {_alpha: 100, time: t, delay: d+pt});
    Tweener.addTween(this, {_xscale: 150, _yscale: 150, time: t, delay: d+pt, transition: "easeoutelastic", onComplete: OutTxt});


function OutTxt() {

    Tweener.addTween(this, {_alpha: 0, time: tO, delay: dO});
    Tweener.addTween(this, {_xscale: 1500, _yscale: 1500, time: tO, delay: dO, transition: "easein"});


animaTexto("t10", 0);
animaTexto("t9", 2);

but show me the text at same time, like do not reading the delay time.
i using mcTweener class.

any idea what can be wrong?
