Should my answer be accepted?
Not too sure if I'm correct but I can't find where I went wrong if I did
var id = "23188xtr"; var lastName = "Smith"; var userName = id.toUpperCase(); userName += "#" + lastName;

The challenge requires you to do the lastName in capitals as well, so try:
var userName = id.toUpperCase() + "#" + lastName.toUpperCase();
