Stuck on Using Strings assignment

Not sure how to do this challenge -Complete the assignment to the userName variable by adding a # symbol followed by an all uppercase version of the lastName variable. In other words, using string concatenation so that the final value of userName is "23188XTR#SMITH".

app.js 
var id = "23188xtr";
var 
var lastName = "Smith";
id.toUpperCase();
lastName.toUpperCase();
var userName = "id"+"character"+"lastName";

Hi Denise,

I would think you need to use the toUpperCase() method when passing those values to username. Also, you have quotes right at the beginning of your value so the code is reading you "id" variable as a string! Keep variables outside quotes. So, I think your line should look something like this:

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

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

Give that a shot and let us know if it works! :)

You're very close on this one. for the var username first you don't need to use quotes on the var names. that turns them into strings. Second just use the character "#" instead of the string "character". Third just add the toUpperCase() method to the var names while your are concatenating the variables and string. so the code should look like this

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