Code (Skript):

1. on rightclick:
2.     player's tool is a compass named "<yellow>Spectate players":
3.         cancel event
4.         set {_slot} to 0
5.         open virtual chest inventory with size 6 named "Spectate players" to the player
6.         loop all players in event-world:
7.             if {spc::%loop-player%} is not set:
8.                 format gui slot {_slot} of player with loop-player's skull named "%loop-player%" to run player command "/teleport %loop-player%"
9.                 add 1 to {_slot}

This is supposed to create a list of players in the current world of the event-executor and make heads which teleport to the corresponding users. But the problem is that nothing after player's tool is a compass named "<yellow>Spectate players": seems to work, I tested with a hello world message and no, don't work, I also see if the name is correctly written and it's correct, maybe lore can have something to do with this, anyway I need help!!!

 

@ShaneBee Yup, I tested with a book and don't works, yes I have worldedit and the compass says that, but I don't have essentials.
@Efnilite Yes, I have issues often with skript, and I'm on the discord of SkUnity, but I didn't ask anything yet there.

 

Probably is better there, but I'm a little more comfortable here than there, any discord server that is not mine or a near friend's one is for me a little unconfortable. So, I'm a little scared. Maybe if you know how to make the code I post there show as a code like in darker gray for highlighting. I don't know how to do that...
