insert fixed text after price at product page

Hi Najeeb,

i realized, that a snippet you gave my 2 years ago is not working anymore:

`Hi @stylebutton,

please add following code into your theme’s functions.php:

add_filter(‘ppom_input_vars’, ‘ppom_change_label’, 10, 2);
function ppom_change_label($vars, $product){

$vars[‘total_without_fixed_label’] = ‘Gesamtpreis: <span style=”font-size:0.5em;font-weight:normal”>inkl. MwSt. zuzügl. <a href=”#”>Versand</a></span>’;
return $vars;
}`

Can you give me a hint, what i have to change, so that it is working again?

Thanks a lot!
Holger
