How can I Code the Score for a D2 Test in SoSci?

Question

I am trying to build a score for the psychological d2 Test. I have 10 questions with 9 Items each and I need to code a mean score over all answered questions.
There is a time limit for answering the 10 questions, so some participants won't have time to answer all 10 questions. Is there a way to calculate a mean score over the questions that will only consider the questions that have actually been anwered?

valueMean() does that by default, but you can also work with valueList() and a custom FOR loop.
