What is wrong with my example?

The error says I did not attach the # symbol between id and lastName vars.

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

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

There is nothing wrong with your code. But to complete the challenge maybe try:

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

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

I think that's just a bug trying to get you to use the += operator. Or try to use double quotes on the "#".

<b>Thank you!</b> I did something similar just after posted the question and passed the challenge!

Your code is fine. I had the same problem when I was doing that one. Try:

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

var userName = id;

document.write(userName.toUpperCase() + "#" + lastName.toUpperCase());

<b>Thanks!</b> I think I went for the similar solution with two new statements, one of which used "+=".


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

Thank you! I appreciate your help!
