I’ve got it working by adding all the previous Verse files needed, but it STILL had errors in it, even tho i was using only epic’s codes alone. I manage to get something working without error by deleting some of the sorting algorithms that he didn’t recognize. tho inside the game it doesn’t work, at least i have a device with codes that are without errors, that’s a start for me 
I would really like somebody to help me or explain how can i replace their “Score system” in side this “build your own race” just by recording player’s total elapsed time instead of the scores. i mean solo-man-racing system for just recording time and putting the player’s name with the elapsed time that’s all. it should me even simpler than what they have there, but i do not know the allowed vars or whatever it is.. so i cannot just learn it from reading their guide because it’s not an option there.
questing is, where can i learn all the available commands or variables and these stuff? i really want to learn but there it is limited to their purpose only.. i’ve red both the topics for persistency and leaderboards ofc, but cannot say i understand EVERYTHING in there.. im still new to this.
Any help please?
