Leslie, thank you for laughing along at the joke.
I was brought up on Mark Twain, and so I have a fond appreciation for dry wit, but I have often been called out for missing the dry humor in various posts, so I was trying to politely cover both bases.
To truly knows what the flashing yellow means, you need to know the vendor, the installed controller & drive models, and review the documentation. That said, in return for your good humor I would be glad to check when I am logged onto your server at no charge; call it good humor credit.
You made me smile as well.
