Hi I am trying to fade in an image using actionscript,

this is the code i have,

speed = 10;  
image.onEnterFrame = function(){  
this.\_alpha\>=100 ? this.\_alpha-=speed : delete this.onEnterFrame;  
}

I’ve set the image on stage to alpha 0, i run this movie but nothing seems to happen, i’ve given the movie clip name an instance name of image.

can someone help?

image.onEnterFrame = function() {
(this._alpha<=100) ? this._alpha+=speed : delete this.onEnterFrame;
}

```

well, go right to the [source](http://www.macromedia.com/support/flash/action_scripts/actionscript_dictionary/actionscript_dictionary021.html).  
anyways its the same as going:

```auto

var speed = 10;
image.onEnterFrame = function() {
if(this._alpha<=100) {
this._alpha+=speed 
} else { 
delete this.onEnterFrame;
}
}

```

It is called a tertiary operator…
