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

Hi there,

For some reason the get_mac_by_printer(host_name) method isn't working.
All the other bits work, but I have a feeling that I'm running into a
problem with variables defined within blocks, but I'm at a loss as to
how to negotiate it. The resulting mac is returning as nilClass and it
definitely isn't nil! Code as follows:

#Class for handling the plist file.
class PlistHash
  def initialize(path)
    @path=path
    @plist_hash=Plist::parse_xml(@path)
  end

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

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

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

Thanks for your help,

Adam
