Quiz NoCodeMonkey

Hello everyone,
I have a problem and hope you can help me. I’m using Nocodemonkey’s quiz component but can’t manage to create a point system. I suspect that I’m still missing some database links.

I would also like to add the possibility of playing against each other with a friend, but unfortunately I don’t know how to implement that. If anyone has experience with this or can give me some pointers, I would be very grateful.

Thank you very much in advance!
