I tried it like this: var userName = id.toUpperCase() + "#" +lastName.toUpperCase(); Im not sure how else to do it

The problem says to take the var userName = id.toUpperCase(); and add on a # as well as an all caps version of the lastName variable.

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

var userName = id.toUpperCase();

Your proposed solution looks okay to me, and it works in this JSFiddle. Another way would be:

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

What error are you getting exactly?

I just did the Challenge you are asking about and it worked using your proposed answer.

The syntax which you used is correct.

It seems the expected output is "23188XTR SMITH"

you can try in the following manner:

(variable) userName (equals) id(dot)toUpperCase()+" "+lastName(dot)toUpperCase();

Thanks guys. I think where I was screwing up was I was thinking that once I tried to store id.toUpperCase in username that once I called username again it wouldnt be all Caps. I think something in the video mentioned that it would only change it in that instance but once you called it again without .toUpperCase it would go back to normal. I may have misunderstood.

After you call

    var userName = id.toUpperCase();

userName has the upper-case version of id, and if you call userName after this, it should still have the upper-case version of id.

id, however, still has the original, non-upper-case string.

There's no reason for userName to revert back to the original, non-upper-case string.

Perhaps what you mean to say is that toUpperCase() returns an upper-case version of the string, but it does not change the original string.

Hey Tim,

Yes, in concurring with Andrew, due to the .toUpperCass() already being applied to var id userName has what you need.

Your concatenation would simply be something like this: document.write(userName + "#" + lastName); if you needed spaces, lol ;-) : document.write(userName + " # " + lastName);
