title: Thickbock data validation in googlespreadsheet how to return multiple values
body: <p>I created a googlespreadsheet here: <a href="https://docs.google.com/spreadsheets/d/1K5oc6-XcgMTUSCICr9GguxHWkrm1UuMhnzXu9Rn3ngY/edit?usp=sharing" rel="nofollow noreferrer">https://docs.google.com/spreadsheets/d/1K5oc6-XcgMTUSCICr9GguxHWkrm1UuMhnzXu9Rn3ngY/edit?usp=sharing</a></p>
  
  <p>I would like to return values from all the "checked" thickboxes in a single row like the image below.</p>
  
  <p>Can I do this using a formula?</p>
