Hi Chris, just one minor bug in the code (see below)

the line above should be inside the following if

>           missing << sym.id2name if value == nil || value.empty?
>         end
> 
>         raise RequiredDataMissingError.new("Required fields not set:
> #{missing}") if !missing.empty?
>       end
