Cant add event block location to variable

[reny_b]

on place:
	if player's held item is coal block named "&7Coal Gen &8- &7[&a1&7]":
		if {GenCount.%player%} < {@DefaultMaxGens}:
			add 1 to {GenCount.%player%}
			add location of event-block to {Gens::%player%} # Problem

You need to use {Gens::%player%::*}. So add location of event-block to {Gens::%player%::*}. Also instead of just %player%, you should use %player's uuid%. This will use the player's uuid instead of the player name and if the user ever changes their name, this won't reset.
