Hi! Welcome to the forum!

I would advise using the ‘ask for help’ button in future, it appears after you fail the challenge a few times. It will automatically share your code, browser info and the lesson link.

For now, please share your code. It is not possible to help without seeing it. Also please share a link to the lesson, then it is easier to check your code.
