What does the workspace mean when it asks if I've called the .toUpperCase to "lastName" in the code below?

see code below. i cannot understand why this isn't valid. What does "Call the .toUpperCase" correction I'm getting mean? I'm very confused.

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

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

Jordan, what it wants is for you to assign an all uppercase version of the id variable to the userName variable. To do that you use the toUpperCase() method on id and then assign the result to userName:

var userName = id.toUpperCase();

Oh! That makes sense. Thank you for explaining it to me.

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