Search Multiple Options

Hi,

I need some urgent help – i purchased the staff list plugin as well as the add-on staff search. On the website i need to have multiple languages to filter by on the search. So a staff can be searched by multiple languages on the staff page i setup with the search filter.

So for example a staff can speak English and Greek. But when i add more then one language on the back-end it doesn’t work on from the search filter.

The page I need help with: [log in to see the link]
