Well you seem to be missing layout files on github so can’t tell where the error is

please pull the project to your pc, create the layout item that is missing and solve the error(issue)

Are you asking us to do your homework/interview question?

No. Help with issue only. Because I tried various forms of adjustment without success despite having made several advances

Sounds like it

sorry I saw the syntax errors from your screenshot. if you cant fix those, then I cant help you

I can if you tell me more about them and about which error screen you're talking about. (error1, error2, error3, error4)

its like in all of them at the bottom..

Sorry, but I think you're wrong.

No
