Hi John,

Thank you very much for your advice. I tried the following code unfortunately without luck.. Nothing changes. Im a beginner at this so I was wondering if you or someone else can advice me on what is wrong?

function my_acf_save_post( $post_id ) {

// Bail early if no data sent.
if( empty( $_POST[‘are_we_counting_participants’] ) ) {
return;
}

// Get values.
$values = $_POST[‘are_we_counting_participants’];

// Update with new value.
if( $values == ‘no’ ) {
update_field(‘number_of_participants’, NULL);
}

}

add_action(‘acf/save_post’, ‘my_acf_save_post’);
