Firstly, you need to pay close attention to the camel-casing with method names.

Secondly, you're passing the variable id as a parameter to the .toUpperCase() method, although it does not take one. The correct syntax is like this:

var userName = id.toUpperCase();

Hey Scott, there is no touppercase() method as such, the one you need is string.toUpperCase();

hope it helps, good luck! Deckey
