Hey, Lenora Tracey Amadi.

The challenge is looking for the following line to append #SMITH to the end of id.toUpperCase():

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

In the real world, you probably wouldn't write it that way especially when the strings start to get long. This is how I would have written it more practically with String Literals:

var username = `${id.toUpperCase()}#${lastName.toUpperCase()}`;

You can read more about string literals here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals

Happy coding.

This challenge doesn't accept template strings. But if it did, you could write it even more compactly this way:

var userName = `${id}#${lastName}`.toUpperCase();

it worked . thank you..
