Hi I have tried to do a few labs and the Banner MOTD bit on the assessment keeps coming up as answered incorrectly

:
The instruction is this
Banner; You are at the R1 Router, Authorized access only!
(no space between the delimiting character and the banner)
I use the banner motd # command in global config mode.
Then type the above request in word for word and it still comes up with a red X in the assessment.
I have even tried copy and pasting it in and it still doesn't work.
Why isnt it working? Arrrgggh
