I am trying to use TweenMax (first time, so theres probably something simple that I’m missing). I open up TweenMax, I set my tween, i copy the code, paste it into my flash, change the name of the movie clip, and when i test it, flash comes back with "1172: Definition gs:TweenMax could not be found.

Install the gs.classes from the downloaded zip file:  
ie: ![](http://www.byrographics.com/AS3/directory.png)

Import the class into your project:

```auto
stop();
import gs.TweenMax;
import fl.motion.easing.*;

```

At this point, you can access the TweenMax class in your actionscripts.
