Numeric-entry fields as pick-many assessment possible...?

Hello experts, 

I am creating a game-like test (with results page). Having used up both the click as well as the click-and-drag interactions of all kinds, I am left with the typing interaction. So, I tried to create a multiple numeric-field question & submit it as a pick-many. While the submission was possible (with feedback display), the outcome is not getting passed on to the Results page. 

Can someone please check the attached file & let me know if this is even possible...? 🤔

Thanks in advance.
