Hi everyone.

I’ve been trying to work this out for the last couple of hours but I don’t seem to get anywhere.

I can’t make the tween to work. I’ve tried hundreds of tutorials and such (and they are all basically the same), I even followed the troubleshooting section of [this tut](http://www.kirupa.com/developer/actionscript/tween.htm) with no results.

If I download any file with that same script it works, if I copypaste it and do the exact same thing it doesn’t. Maybe is something very simple that I just can’t see but this is driving me nuts.

Partial code from flash tutorials:

```auto
import mx.transitions.Tween;
import mx.transitions.easing.*;
new Tween(ball_mc, "_x", Elastic.easeOut, 0, 300, 3, true);

```

If anyone could give me a hand at least pointing me to a solution that would be great.

Thanks in advance.
