Hi,
I suspect two possible reasons for a crash:
* using "#{name}" inside a definition of name is pretty certainly
infinitely recursive - "name" will call itself again and again until
the system runs out of memory
* name is now a commented out field - so there is no field to
substitute
Try changing to
def name
"#{company}, #{address_1}, #{city}, #{state}, #{postalcode}"
end
More likely to work. :)
