Hi all,

I have wrote a function to fade in a movieClip, but it doesn’t seem to work and I carn’t see why?  
I have a MC on the stage with 0 alpha and a btn to call the function.  
I’m sure it’s something simple.

```auto

function fadeIn(num) {
 this.onEnterFrame = function() {
  this._alpha += num;
  if (this._alpha>=100) {
   this._alpha == 100;
   delete this.onEnterFrame;
  }
 };
}
one_btn.onRelease = function() {
 one_mc.fadeIn(10);
};

```
