Kill player on Void

[Kampfwombat]

Hello everyone, i was trying to make a skript that kills every player in the void.
I dont know how to put the code in the thread, but i used:

on damage of a player:
if damage cause is void:
cancel event
kill the player
but I get the error:
"Cant compare a damage cause with a types.art"

Is there a way to work around this? Maybe with coordinates?

Try this, (not tested)

on damage:
  if player's y-coordinate is smaller than 0:
    kill the player

idk if works
hope it help
