The challenge states "Use the JavaScript .toUpperCase( ) string method to assign an all uppercase version of the id variable to the userName variable". The code they give you is the following:

var id = "23188xtr";
var lastName = "Smith";
var userName

There is no need to create/declare a "new" variable as you did on line 3. On line 5 you are appending the userName variable to the new variable you created, but userName does not have a value, so new remains unchanged. Also, you didn't capitalize the n in username on line 5 which will probably throw an undefined error. All you need to is assign the uppercased value of id to the given userName variable as I've shown below.

var id = "23188xtr";
var lastName = "Smith";
var userName = id.toUpperCase();

:point_right: It looks like you assigned to the wrong variable.

You seem to have correctly created an all uppercase version of the id variable, but you assigned it to a variable named "new" instead of the one named "userName" as requested by the challenge. There's also some extra stuff that does't seem related to the challenge.

You may also want to review the videos on Combining Strings and Working with Strings and Finding Help.
