I'm adding the "#" character in between but it's still not working.

see title

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

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

these are all good answers! for me personally I would want to use one variable instead of have to write it the variable three times. so the code can also look like this:

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

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

So you can concatenate everything into just one variable, and make it look clean. the other approach works just as well! I just wanted to show another style of performing the same task.

Hi Caitlin,

You are not using the variable names when using the toUpper method. You are using strings.

So this:

var userName ='id'.toUpperCase();

Sets userName to 'ID'.

You want it to be "23188XTR".

So you should do:

var userName =id.toUpperCase();

Same with lastName.

Hugo's correct, but you also need to flip the =+ to +=
