Adding to a string

The first question asked to declare a variable and turn the string into uppercase. var userName = id.toUpperCase(); var userName

The next step asks you to add "#" and the variable lastName to the end of the username string.

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

I keep running into an error and cannot figure out how to get the variable userName to return the id number plus "#" plus lastName in all uppercase.

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

You got this. Just a typo and a redeclaration not needed at the end

var id = "23188xtr";
var lastName = "Smith";
var userName = id.toUpperCase() + "#" + lastName.toUpperCase(); // note, lastName with a capital N
// no need to redeclare var userName; at the end as that would make userName a null value;

I've tried that answer and it keeps telling me that my task1 is no longer passing. Which was declaring userName with just the id and .toUppercase method. So confused!

sorry, forgot to mention make sure to include parenthesis () to both toUpperCase methods.

I've been coding for years, and I make that mistake frequently on the toUpperCase() method. :)

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