Simple problem

1

I have the code for a side scrolling shooter and I was wondering if someone could help me with a problem i have. I need help witht he ducking crawling. It wont play the anim corectly. What am I doing wrong?

 onClipEvent (load) {
//Variables
this.vel = 0;
this.falling = true;
this.gravity = 2;
this.speed = 8;
this.shooting = false;
this.bulletspeed = 30;
this.bulletspeed2 = 30;
this.duck = false;
this.aimup = false;
}
onClipEvent (enterFrame) {
//movement
if (Key.isDown(Key.RIGHT)) {
this.gotoAndStop("running");
this._xscale = 100;
_x += this.speed;
}
if (Key.isDown(Key.LEFT)) {
this.gotoAndStop("running");
this._xscale = -100;
_x -= this.speed;
}

this.gotoAndStop("ducked");
this.duck = true;
} else {
this.duck = false;

this.gotoAndStop("crawlin");
