sub main()
{
  CUSTOM_MESSAGE = "TEST";
  i = GetInterfaceObject ($node, $1);
  include_node = false;
  switch ($node->ipAddr)
  {
      case "10.230.0.212":
        if (i->name == "gi7")
        {
            CUSTOM_MESSAGE = "PC to Switch Test Interface";
            include_node = true;
        }
        if (i->name == "gi2")

            include_node = true;
        }
        break;
      default:
        include_node = false;
  }
  return include_node;
}

My Message Text in Action Configuration for email looks like this:  %n - %m - %M

I am getting the email for the correct interfaces and the first 2 parameters for the message (%n and %m) are being passed but the CUSTOM_MESSAGE (%M) is not being displayed.

Any ideas?

Thanks for any help.
