Before we look at completing the challenge, let's look at your code for a moment. As you can see, you have two variable definition statements for the userName variable, and one is also missing a semi-colon to terminate the statement.

Start off by deleting both of these definition statements.

Now we can start over and create a new variable named userName and assign it the the value of the Id variable:

var userName = id;

Now, to convert the value of the Id variable to an all uppercase string, we need to use the toUpperCase method on it:

var userName = id.toUpperCase();

Now the userName variable holds an uppercase version of the string in the id variable. From your question, I have added an answer that you have asked, if this doesn't provide the correct code for the challenge, you would need to be more thorough with your question.

Hope this helps.
