Stuck on the question

I'm a bit stuck on this question because it's adds '#' but I'm not sure how to concat it??

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

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

Keep in mind that the error message you're seeing is just a good guess.

If you're sure the # is added in there, then double-check the other requirements of the challenge and make sure those are being met. Like for instance, if the challenge requires ALL text to be capitalized you'll need to figure out a way to capitalize both of the entries, not just the last one.

The code I posted above definitely passes one of the challenges, so make sure you're not further along and have another requirement. The good news is that you got ride of the error message complaining about assignment and left- or right-handed values, right?

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

That second operator, +=, might be thorwing things out of order a bit, since you're telling js to take everything to the right (i.e. '#' + lastName.toUpperCase() ) and assign it to the left (i.e. id ) then.... assign it to the variable ( i.e. userName )

If the format you have is what is expected, try this:

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

Hey Gavin,

I am having the same issue. I tried just waht you said above, and I get the same "Bummer did you add the '#' between the id and lastName variables" error that Johnny was getting.

Any thoughts in to what is causing this?

UPDATE: Nevermind, I found my mistake, it was a syntax error, I had an extra semi colon. After taking it out this worked!

When you say it doesn't work, are you saying that there's an error message in the "Bummer!" warning bar in the code challenge, or is it saying that it's just not getting the response it wanted?

Do both words need to be capitalized?

Yes, I'm getting an error message saying 'did you put the '#' between id and lastName?'
