I’ve edited your code 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 (').
Notice the syntax highlighting of your code looks “off”. This is because there is some syntax that is not HTML.
I suggest you reset this step, and try again. If you are still stuck, return here, and we can try help you further.
