The code challenge is looking to see if the proper uppercased string is inside the variable, not printed to the document.

You don't need to print it out to the page using document.write(). You need to assign the uppercased version to the userName variable.

maybe

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

The toUpperCase() method only returns an uppercase version of the string; the string inside the variable doesn't change. You ned to assign the upperCased string back into the variable. This is one way"

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

I understand thank you, I was trying: var id = "23188xtr"; var lastName = "Smith";

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