Subject: Error - "`+': can't convert nil into String"


Why does the code below give me this error? What can I do to fix it?

/people3.rb:4:in `+': can't convert nil into String (TypeError)
om C:/Ruby192/people3.rb:4:in `to_s'

class Person
attr_accessor :fname, :lname, :age
def to_s
"hi " + @fname + ", " + @lname
end

end



Thanks
