PHP Navigation problems?

[Technocrate]

I am trying to create navigation using PHP to update my website automatically when an extra button is added. I have followed an online tutorial, but it doesn't seem to be working.
I have created a PHP file for the navigation and then my usual html file. I have used 'include', but I'm not sure if I have coded it incorrectly.

We need your code and not a website link as we can't see your PHP through it.

Sorry just had to make sure.
