Create a calculatedmulti question, name the question with a multilang name. Save. Return to the question bank and click to edit that question. Check beside the "Question stored name" label that the question name is displayed in your language Create another calculatedmulti question with a name like x < 1 && x > 0. Repeat the test with that.
