Hi and welcome to the forum. The best way to get help is to use the Ask for Help button. This will create a new post where you can describe your issue and post your code instead of a screenshot.
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.
