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

Hi Arno. As a new variable, you can't use '+='. You can only use the '=' symbol when setting a new variable. Plus I doubt you can have '+=' in the same line twice.

But try this:

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

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