Message description in member top menu

How to get the message description ( __message_descr__ ) that works in mail_box.html to work in the member top menu mailbox dropdown. ( mail_box_member_menu_messages.html )

If i paste __message_descr__ in mail_box_member_menu_messages.html i don't see anything.

for pop up: check how the code gets filled in what function in wich php file. Then add the 'message_descr' => $sanyfieldvalue;

then clear your cache it will work i guess. I uses a different function/functions
