I've created the hash and can store all keys and values however I'm 
trying += to add the balances which is value in the hash.  So far the 
accounts that have the same number are not being consolidated into one 
key, value....  Can someone tell me what I'm doing wrong with this?

Thanks,
Tim

  sktylist = Hash.new("")
            sktylist[@acctnum] += [value]
         p sktylist
