True / False doesn’t appear

Hello,

I’m starting to build my website. I use ACF to help me on my task, all works good. I enjoy to use this plugin, but I have a question for a field. I use true/false on my page for a field and the php code generate by this plugin doesn’t appear on my website.

I don’t understand why, I activate my field and read this code:

div>
            <?php echo "<strong>Traduction fran?aise:</strong>"; if ( get_field( 'traduction_francaise' ) == 1 ) { 
             // echo 'true'; 
            } else { 
            // echo 'false'; 
            }  ?> 
        </div>

whatever I choose, nothing appear on my website, if true it must appear “oui” and false “non”. But I have nothing. Why?

The page I need help with: [log in to see the link]
