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

app.js
var id = "23188xtr";
var lastName = "Smith";
var res=str.toUpperCase();

var userName= id;
index.html

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

Instead of naming the variable you wanted to change, you had named the function you're using that is you were meant to say:

var userName = id.toUpperCase();

so that a Upper case version of id is assigned to username.

Right now saying str.toUpperCase(); makes the computer look for a variable named "str". You had to substitute the variable name. Hope this helps, mufesi wangu.
