Exact percentage score vs 0% score in Storyline

Hi all,

I try to achieve the following:

• User answers a single slide question and has 6 out of 10 drag&drop targets correct on that slide
• Score is updated in results slide with 60% correct

Easy enough, but i do not see a possibility to do that.

I do not want 0% correct as suggested by storyline, as this is

1. Not engaging for the learner, and ...
2. .. just not correct.

I tried the following already, which is not correct for sure:

 I could also do this, which does not help either:

 Do you have an idea how to achieve this?
