Subject: changing hash key

I am working with a script to record accounts and their balances.  I
need to check the key in a hash and if the account number is already
there just add the blanace to the value. So far this is what I have and
its not quite doing what I need.  Is my test not right?  I get all the
account numbers and their balances instead of a list with the accounts
and balances without the duplicate account numbers.

Thanks,
Tim

  sktylist = Hash.new("")
              if sktylist.has_key?('@acctnum')
                sktylist.merge!('@acctnum' => 'value')
 else
                sktylist[@acctnum] = [value]
              end
              sktylist.each { |key, value| puts "#{key} equals #{value}"
}
