Add target-block to {zmienna grupowa}

Cześć, mam taki skrypt:

on break:
	if player is in world "test":
		if {bewaar.Krolestwo3v3.status} is 3:
			if {bewaar.Krolestwo3v3.block::%target block%} is not true:
				cancel event
				send "&cNie mozesz zniszczyc tego bloku!" to player
		else:
			if player doesn't have permission "protection.break":
				cancel event
			
on place:
	if player is in world "test":
		if {bewaar.Krolestwo3v3.status} is 3:
			add target-block to {bewaar.Krolestwo3v3.block::*}
		else:
			if player doesn't have permission "protection.place":
				cancel event

No i mam pytanie bo jak jest "add target-block to {bewaar.Krolestwo3v3.block::*}" no w sensie bo wyskakuje mi błąd, że "target-block can't be added to {bewaar.Krolestwo3v3.block::*} becouse the former is not an object", więc jak dodać blok do zmiennej grupowej? (nie ogarniam tych zmiennych grupowych )
