this works but repeatidly fades in and out. I need to know how stop this after one loop and where to insert the script.

MovieClip.prototype.fade = function(minAlpha, maxAlpha, speed) {  
this.onEnterFrame = function() {  
if (!this.trigger) {  
this.\_alpha -= speed;  
if (this.\_alpha\<=minAlpha) {  
this.\_alpha = minAlpha;  
this.trigger = true;  
}  
} else if (this.trigger) {  
this.\_alpha += speed;  
if (this.\_alpha\>=maxAlpha) {  
this.\_alpha = maxAlpha;  
this.trigger = false;

```
                    }
                    
                {
                }
            }
    };

```

};  
clipToFade.fade(0, 100, 5)
