id is a variable which contains a string. toUpperCase() is a method which we can call on strings, and you've have one little typo here: you have an extra close parens ) at the end.

id.toUpperCase() is going to return a value, and we want to use the assignment operator = to put that value into the variable userName:

var userName = id.toUpperCase();
