Hi Harmandeep, thanks for asking. You almost got the solution, there was one detail left.

You can concatenate any kind of strings/characters with the + operator. To add the # symbol to your userName variable, you simply have to do this: 

var userName = id.toUpperCase() + '#' + lastName.toUpperCase();

Happy coding.
