Currently I'm trying to create a system that only allows certain command block events to trigger once to each person. Rather than setting up a system at the spawn to set the starting value for the points objective for each new player to 0 I want to create a series of command blocks to check if the player's points value is less than a certain number (to prevent them from triggering it multiple times). I hope that it could also apply to undefined starting values, that way new players could still trigger it the first time as well.
I've come up with an unsuccessful solution
and would appreciate any assistance with this predicament.
