The variable is correct and yet...it's not correct?

I am attempting to have the userName variable equal 23188XTR#SMITH apparently that is what my code is putting out. However the error message reads - the 'userName' variable is "23188XTR#SMITH" not "23188XTR#SMITH".

Is the code not written entirely correct?

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

var userName = ('id'.toUpperCase());
userName = (id.toUpperCase() + '#' + lastName.toUpperCase());
index.html 
<!DOCTYPE HTML>

What happens is: L1. Stores '23188xtr" into 'id'. L2. Stores 'Smith' into 'lastName'. L4. Stores 'ID' into 'userName'. ('id' is a literal string containing the value 'id', not a variable reference to L1's var. L5. Concatenates '23188XTR' + '#' + 'SMITH' into '23188XTR#SMITH' and overwrites the previous value of 'ID' that was assigned into 'userName' on L4. As an aside ('id'.toUpperCase()); is unnecessary to enclose in parens, as is with L5.

Andrew, close, but you need to make id upper case, and then use that in the next line:

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

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