did you really check that? it will always return "value 1" ;)

then just create it
eg,

> def value_name3(value)
>   VALUES.each{|k,v| return k if v== value}
>   ""
> end
=> nil
> value_name3 1
=> "value 1"
> value_name3 2
=> "value 2"
> value_name3 3
=> "value 3"
> value_name3 4
=> ""
> value_name3 "asdf"
=> ""
