Looks to me like you need to include the [script.aculo.us](http://script.aculo.us) library,  
which is found in your public/javascripts/ folder. However, add this  
to the of your application layout:

\<%= javascript\_include\_tag :defaults %\>

Then make sure that everything is in the javascripts folder.
