Description of a custom fields after the name and the values (at the end)

[mehdi09]

Hello everybody,

-How can I display the description of a custom fields after the name, and the values ?

You can see it alive here http://tamel.fr/v3/index.php/sites-internet/site-presence-detail
or you can see the screenshot I made
I know that I have to edit the default_addtocart.php, but I don't know how and what.

Thanks a lot for your help,
