not sure where i'm going wrong...

Use the JavaScript .toUpperCase( ) string method to assign an all uppercase version of the id variable to the userName variable.

Bummer: The userName variable is "23188XTR#lastName" not "23188XTR#SMITH".
app.js index.html

var id = "23188xtr"; var lastName = "Smith"; ā€‹ var userName = (id.toUpperCase()); ā€‹ userName += "#lastName"; ā€‹

app.js 
var id = "23188xtr";
var lastName = "Smith";

var userName = (id.toUpperCase());

userName += "#lastName";

So the problem here is that the last line of your code is concatenating the id in upper case with #lastName (the literal string).

The challenge wants you to concatenate the id (upper case) with a '#' and the value of the lastName (upper case) variable.

Consider the code below:

var fName = "Sam";
var lName = "Weeks";

var fullName = fName.toUpperCase() + " " + lName.toUpperCase();

The above variable fullName would be assigned "Sam Weeks".

Ok so my example is using variables that you shouldn't be using in this challenge - it was to try and emphasise the point. You should continue to use userName, as that it what the challenge expects to see.

userName should contain this exact value: 23188XTR#SMITH

As the lastName variable contains "Smith", we can use this variable along with the .toUpperCase() method.

Here's an example:

var id = "2111otf";
var lastName = "Weeks";

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

The above code would result in the userName variable having the value: 2111OTF#WEEKS
