General help

Hey everyone, 

I wonder if there is a possibility for the restricitons. 
When setting up a course i need to cpmplement them in 3 different languages. Therefore, i need to set the restriciton that the right course with the right language appears depending on which language the user is presetting. 

The problem: 
When setting restricitions you can set, that either one of the restrictions need to be fulfilled or all of them. But I also give certificates after the completion of a course, which have a restriciton " course must be completed" before getting the certificate. But now the language settings when you try to insert more than one langugage additional to the "completion" won't work. 

I need the courses to be displayed in english for the english language setting and the chinese language setting including the certificate  requirement. 

any help? 

Cheers
