Hi and welcome to the forum!

How exactly are you stuck? What do the failing tests say? What is the link to the challenge you are working on?

If you have a question about a specific challenge as it relates to your written code for that challenge, just click the Ask for Help button located on the challenge. It will create a new topic with all code you have written and include a link to the challenge also. You will still be able to ask any questions in the post before submitting it to the forum.

Thank you.

I’ve edited your post 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 (’).

Thank you so much for your assistance Jeremy, I accidentally figured out my mistake. A little bit difficult to recognize common sense or logic yet, but I don’t give up and would like to cope. )
