Quick ActionScript Question for a Newbie

Greetings,

I have a movie clip I am moving from the left side of the stage to the right using AS, however I can’t seem to get the clip to scale larger or stop.

I was able to succesfully get the clip to move, so I am wonderging if anyone can help me stop the MC and gradually make the clip larger.

Here is the AS as it stands now -

onClipEvent (load) {
_x=24;
_y=111.7;
_xscale=_yscale=0;
_alpha = 10;
}
onClipEvent (enterFrame) {
_x=_x+3;
_xscale=_yscale=+100
_xscale=_yscale=+100;
_alpha = _alpha+2;
}
onClipEvent (data) {
stop();
}

All help is greatly appreciated.

Best,
CG
