This has come up on the list before...
'words' needs to be a global variable or constant. It's basically a typo 
in the tutorial.
Changing it to Words will get you a constant, changing it to $words will 
get you a global variable.

When you require a file, the local variables in that file stay in that 
scope, and are not imported into the current scope. To be able to access 
them, you must make them global.
