There is a syntax error in the 'overlayOpacity' setting though. The value of the setting needs to be wrapped in double quotes like this: http://screencast.com/t/r39nxRG5Y
Currently the source looks like this: http://screencast.com/t/ytQyERld . Which means that you're having a decimal value in a comma array and it breaks the code. Wrapping the "0,3" (or whatever the value of the setting) in double-quotes fixes the problem.
All the best,
