Geez, Louise!  Lighten up on the wide indentation!

Two spaces is plenty for Usenet.

Of course not.  You cannot declare a method inside another method!

Because you don't define it in this method.  You have to define it, as a 
method argument, a class member, or something.  As a method argument, you have 
a way to declare it and get it into the method.

OK, your whitespace is crazy.  You have eight TABs (anathema on Usenet) and 30 
spaces indentation on these lines.  Come on, have a heart for the people from 
whom you are requesting aid.

I recommend a thorough study of the tutorial:
