Finally, add a # symbol and lastName in uppercase to the end of the userName string. The final value of userName is "23188XTR#SMITH".

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

String values need to be wrapped in quotations- In this case, Smith is seen as an undeclared variable. You also want to try to make your code as concise as possible so calling toUpperCase() more than once in inefficient. Try this:

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