Add text before socials buttons

Hi,

Thanks for this great plugin!

I have read topic (http://creativejuiz.fr/blog/doc/juiz-social-post-sharer-documentation.html#hooks) which explain how to add text before the buttons in file functions.php but in my file functions.php i don’t know where to put the code:

<?php
if( !function_exists(‘before_the_jsps_plugin’)) {
function before_the_jsps_plugin() {
return ‘<div class=”another_container”>’;
}
}
add_filter(‘juiz_sps_before_the_sps’, ‘before_the_jsps_plugin’);
?>

When i try to put the code in my file, nothing appears…
