Hi Patrick,

The error "Record does not accept input" happens when you send a string (parsed with %s) to a record with an enum VAL
like your mbbi, but the string does not match any of the enum strings in the record.
As your record only has "STANDBY", "OPERATE" and "SELFTEST", it does not accept the input "MONITOR".
