Hi Beth,

You are using the method correctly. You are just using it on the wrong variable. Right now, you are re-assigning a value to the id variable (you are removing the value that was there and are replacing it with an upper-cased version of the lastName variable. When the instruction say to

assign an all uppercase version of the id variable to the userName variable.

Here, the challenge has provided the new variable userName for you to use.

So, you need to delete the line of code you added, and just assign the upper-cased version of id (not lastName) to the userName variable (not id).

Hope this helps clear things up. :)

Keep Coding! :dizzy:

var id = "23188xtr";
var lastName = "Smith"
console.log(lastName = toUpperCase();
var userName

Moderator added Markdown so the code is readable

is this close?

Not really. You're still not using the correct variable that was provided.

You're first one was correct in syntax, just not using the right variables. (And the challenge doesn't say to include a console.log method).

Because you did have the correct syntax above, I will include the corrected code for you now. Have a look at what you had originally, the answer I provided above, and the corrected code below. Hopefully you will see where I was going with my first response and that it'll make more sense now.

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

var userName = id.toUpperCase();

Also, when posting code (copy / paste) style, please refer to the Markdown CheatSheet for formatting rules, otherwise the code is pretty unreadable in the Community posts. I have corrected you comment to include Markdown formatting.

Hope this all helps now. :dizzy:
