Add a page template

Hi !

First of all, well done for this template. It looks and works really well 😉

For my website, i need to create a new page template.
I tried to call my file “newpage-template.php” and i can’t find it on the toolbox (page template) when i edit my page. I’ve already made it with others templates but i can’t do it with this corpo template.

I also tried with “newpage-page.php” but it doesn’t work better !

BTW, i added this into my file :
<?php /* Template Name: New page */ get_header(); ?>

Please, would you explain how i can add a new page template ?
Cheers,
Toni
