Iâ€™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.

See this post to find the backtick on your keyboard. The â€śpreformatted textâ€ť tool in the editor (`</>`) will also add backticks around text.

Note: Backticks are not single quotes.

You need to give us more to go on than just your code. Whatâ€™s going on? What is your code supposed to do? What problems are you having? What else have you tried? How can someone help you?

Okay, right yes, and firstly thanks a mill for your advice. So I entered the code, and usually it gives the â€śerrorsâ€ť feedback. I uploaded a screenshot

whatâ€™s your code supposed to do?

you have not said that. canâ€™t debug without knowing what should happen and what is happening instead
