You need to add a secret from a padlock icon present on the top left side. Add secret as below :

Hello there.

Thank you, for your contribution. For future contributions, please wrap your solution within :

````plaintext
[details]
```
code goes here...
```
[/details]

````

Also, provide **all** of the necessary code to pass the challenge.

Also, 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.

 ![Pre-formatted-text](https://global.discourse-cdn.com/freecodecamp/original/3X/1/b/1b18854f1059217f29370444396145cc3a0cd8ae.gif)

See [this post](http://www.freecodecamp.com/forum/t/forum-code-formatting/25574) to find the backtick on your keyboard.  
**Note:** Backticks (`) are not single quotes (’).
