You are genius. It was a zero and not an O, although I cannot understand why when I copied it from the phone and pasted it into the dialog box.
Now I am really stuck and I regret asking for so much help. I think that once I get this provisional testing thing worked out with Apple, I will be on my own. Can you look at the attached JPG.
When I put in the name for the device, I used Greg. (It was a clean phone given to me by Greg.)
Now I am so confused by the process, I don't know what to change next. Please advise and thank you.
