I’m trying to fade in some text at a certain point in my movie. After reading the tween class tutorial, I grabbed this snipped of code, slightly modified to be:

```auto

import mx.transitions.Tween;
import mx.transitions.easing.*;

var fadeIn:Tween = new Tween(myTextMovieClip, "_alpha", Elastic.easeInOut, 0, 100, 2, true);

```

Now, when I run my movie this works just fine. But the thing is, I don’t want it to run until a button is clicked in the movie, and the movie clip will not be visible until that button is clicked. So how would I have this tween fire off when the button is clicked? How do I connect them?

Would it be something like this?

```auto

myButton_btn.onRelease = function() {
   myMovieClip.fadeIn;
}

```

??

Thanks
