Please explain in your own words the issue you are having.

I’ve edited your post to improve the readability of the code. 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.
