How to combine strings

in task two of the code challenge of combining strings, the instructions are to complete the challenge to the userName variable by adding a # symbol followed by an all uppercase version of the lastName variable.

I followed the instructions, but received this message, Oops, It looks like task 2 is no longer passing. What am I missing?

app.js
var id = "23188xtr";
var lastName = "Smith";

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

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

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

You added an extra semi colon after id.toUpperCase() and also added an extra .id to the lastName part.
