Undefined local variable or method `code_words' for main:Ob

I have the problem:

undefined local variable or method `code_words' for main:Ob

I'm trying to work on an example from the Why's poignant guide to Ruby,
and don't know why I'm getting the preceding error.

I just made some small changes in the example, and they are not related
to the syntax, just the fill outs.

The first .rb is "wordlist.erb": http://pastie.org/1031629

The second one, "idea.rb": http://pastie.org/1031631

Provided that the Ruby version I'm using is: ruby 1.8.6

So, any idea how I can workaround this issue?

Thanks.

Please omit the last comma in wordlist.rb. But, I'm still having the
problem. Appreciate your collaboration.

Local variables are not visible outside of the file they are created.
You will to make code_words a global variable ($code_words) or a
constant (CODE_WORDS). I think for an example like this one those are
the two simplest ways.
