Welcome, nguyenhachau.
If you are wanting to contribute a solution/hint to a guide post, could you please provide a link to the guide post in question, as well as all of the necessary code to pass the challenge.
When you paste the code, wrap it within [details] Code Solution Goes here... [/details] to prevent spoilers for others.
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.
See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
