Use the JavaScript .toUpperCase( ) string method to assign an all uppercase version of the id var to the userName var.

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

var userName

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

var userName =.toUpperCase("23188xtr")+("Smith");
index.html 
<!DOCTYPE HTML>

When you use "dot" notation to reference a method (like "toUpperCase"), the name of the thing that the method will work on must go on the left side of the dot.

Also, "toUpperCase" doesn't take any argument(s).

And don't repeat the literal strings already assigned, just use "id" and "lastName" to refer to the contents.
