Hi @felderregina11 !
Welcome to the forum!
As mentioned, please provide a link to the lesson because none of us knows what you are working on.
We want to help but we don’t have enough information right now 
Also, here is how to write code in the forum
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 (’).
