Hello, it seems that you trying to use the .toUpperCase() and .toLowerCase() methods on strings, which are values of the variables "id" and "lastName". To use these methods according to what the quiz is asking, you would need to call the method on the actual variables itself. It also asks you to use string concatenation to add a "#" in between these two variables. Lastly, the challenge asks that you use only .toUpperCase() so .toLowerCase() is not needed here. The code should look something like this.

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

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

hope this helps!
