Need help with coding

[epm1013]

I'm working with a book called "PHP Solutions" by David Powers.
I created a form exactly the way the book describes along with the php to put into my MySQL database. However, I get "Method Not Allowed
The requested method POST is not allowed for the URL /index.html." when I try a test in the form. Can someone suggest where I might have went wrong in my coding?

From what I read.. you need to make your file a .php

Unless you did this.. anytime I get an error message I have never seen before.. I copy the exact text and, using quotes!!, paste the error in google. You definitely aren't the first person to have the error... so you'll almost always be able to find something like 8000 solutions from google.
