Subject: sort hash, hash key and val off by one, see attached

Please help me with this. I have been trying for days to get this right.
I don't see a next method for a hash. Just don't know what to do. Thanks

Temp1.txt
----------
PersonID,PersonID
ID,ID
LastName,Social Security <need to set this val to "no value”
Social Security, Address <set this key and value to Social Security..and
so on
Address,Unique ID
Unique ID,Potassium
----------

The LastName, Social Security line tells me that there is no value for
LastName and the next value in the list should be changed to the value
where Social Security instead of Address.

(my project consist of me comparing 2 files, there is more to it, but i
just wanted to explain what I am stumped on at this point.)

File.open('Temp.txt', 'r+') do |temp|
  rows  = {}
  temp.each_line do |line|
    key, val = line.chomp.split(",",0)
    rows[key] = val

    #method to store first value
    def storeKey(key,nextval = false)
      storedKey = key
      return storedKey if nextval == true
    end

     rows.each do |attrib|
      if rows[key] != key then
       @@newKey = rows[key].to_s
       val1 = storeKey(@@newKey)
       val2 = storeKey(@@newKey,true)
          #if val == nextkey then replace with 'no value'
           if rows[key] == val2 then
              rows[key] = 'no value'
          end
        end
      break
    end
   end

end
