Why do my html files give Internal Server Error?

I attempted to work on New York Fashion Week HTML project on my computer. If I create the file in WebServer/CGI-Executables (where I am storing my python scripts), the file gives me an internal server error even though it works when I place it in WebServer/Documents. I don’t know what I am doing wrong.

Can you take a picture of it?
Maybe I can help you out.

if it gives you a server_error server refused to respond then you should make shure you downloaded ISS and that you start debuggung when you have the main HTML page open
