Subject: Re: Can anyone tell me why my code isn't working?

Solved it.

I came up with this solution to force the each loops to return a 
specific value from the array of hashes. Explicitly returning the value 
of the block each block did the trick. Still don't think I've got the 
hang of variable scope though. :-(

class PlistHash
  def initialize(path)
    @plist_hash=Plist::parse_xml(path)
  end

  def get_mac_by_host(host_name)
    servers=@plist_hash['servers'].each do |s|
  return s['mac'] if s['name']==host_name
  end
  end

  def get_host_by_printer(printer_name)
  printers=@plist_hash['printers']
        printers.each do |v|
     return v['server'] if v['name']==printer_name
     end
  end
  def get_mac_by_printer(printer_name)
     host=self.get_host_by_printer(printer_name)
   return self.get_mac_by_host(host)
  end

  def get_broadcast_ip
    broadcast_ip=@plist_hash['broadcastIP']
  end
end
