Hi Boris, when you create the msg variable and create the string with firstName, lastName, and role, just attach toUpperCase() to role in the string:

role.toUpperCase()

thank you Bert, i appreciate your support, the mistake was adding ' . ' at the end, after: toUpperCase(); method, thank you a lot, by
