There’s nothing wrong with asking that question. We just ask people not to make multiple topic posts for the same lesson if they’re stuck on it because it starts to clog up the forum.
You copy the code from the lesson.
Then you paste the code into the forum and format 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 (').
