Photos/screenshots of an error can be helpful, but it also helps to provide the complete code. Posting the code helps us help you better!
When you enter a code, 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.
I can’t read the piece of code you have highlighted from the picture. If you want us to read any of that code you will have to post it in the forum. If it’s not relevant to your enquiry delete the picture.
