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

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

  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

If this is for task 1, you're creating the correct thing, but assigning it to "idupp" instead of "userName".

But if you're on task 2, you'll need case conversion on the name also, plus you need to insert a "#" in between the other terms.
