is the correct command userName += "#"; ? Where do I put it in the sequence?

I am a little stumped :/

app.js 
var id = "23188xtr";

var lastName = "Smith";

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

For the second part of the challenge, you have to use the toUpperCase() method on both id and lastName and keep the hash # in the middle with quotation mark around it. Something like 

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

Hi Emily, Abraham is right, but to answer your question about += ... That is the symbol used when you want to add to (either an incremental value or a string) to a variable.

For an incremental value example

var a = 2;
a += 4; //the variable will now equals 6

For adding strings example

var a = "Hello";
a += " "; // a space
a += "World!" // the variable will now be the string "Hello World!"

I hope that helps you.

Jason :)
