Hi Jeremy

Thanks for the tip.  I understand my error and I believe it is the same 
for my "c" method as it is also included in the attr_accessor.  I have 
removed these and I now have the following:

"undefined method `myarray' for nil:NilClass (NoMethodError)"

This error is referring to puts my_top.c.myarray.inspect

Any ideas?  Do I have a scoping issue here?
