I’m trying to use Caurina Transitions in Flash Cs4, As3, but get the error message:

5007: An ActionScript file must have at least one externally visible definition.

I’m simply using this code as test:

```auto

import caurina.transitions.*;

Tweener.addTween (box,{x:10,time:1 });

```

What can be wrong?
