Ho Jacob,

Sorry, there is no bug... but there is a syntax error in your code. That error almost always means that a syntax error was introduced into the current task you are working on, and that is what breaks the code checker.

If you look at the error message you are receiving when checking your code it will tell you exactly where:

There was an error with your code: TypeError: 'undefined' is not a function (evaluating 'lastName.tpUpperCase( )')

Here, it is saying the it was trying to evaluate the toUpperCase() method, but it came back as "undefined". This is because you have a typo in the method name. You have tpUpperCase(). If you correct the typo, the challenge will pass.

Also, on other note, it is not a good idea to put spaces in the parenthesis for the method. This could lead to issues down the line, as a space is a character, and if the method is not supposed to take any arguments, the space could be misread.
And on the topic of spaces, it is a good idea to space out the concatenation symbols. It's really hard to read the code when everything is smushed together:

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

Other than that, nice work! :) :dizzy:
