I think you want something like this: tagsets = [['Police, Crime, Drugs','Crime & Law Enforcement'], ['Fire, Emergency Services','Emergency Management'], ['Schools, Colleges, Libraries','Education']] tagsets.each do |tagset| broad, topic = tagset broads = broad.split(",").map {|s| s.strip } puts "Broad: #{broads.join("; ")}\n\tTopic: #{topic}" # etc. end David -- Rails training from David A.
