Hi @bushra.ghames2707 !
Welcome to the forum!
it will be easier to help you if you write your code instead of posting pictures.
Also, please provide a link to the challenge you are working on 
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 (').
