Right code but still does show undefined

I have used the right code in a camelCase challenge but it still shows undefined and I can not move forward to the next challenge.

var studlyCapVaR;
var properCamelCase;
var titleCaseOver;

studlyCapVar = 10;
properCamelCase = "A String";
titleCaseOver = 9000;

Welcome there,

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

@Anita89 ,

In var studlyCapVaR; you have R and while setting value for studlyCapVar = 10;, you have small r.

Hi, thank you for your help, but unfortunately it still does not work and shows undefined after changing it.

what is your code now?
