Some hints:

  • You can convert lastName to uppercase by using toUpperCase() just like you did with id
  • You can concatenate the converted lastName by using the + operator just like you did with "#"

Thank you for your feed back. Im just not understanding if I need to make a new variable or just add onto it.
