Usuwanie dźwigni i tabliczki

Działa to tak że jak spamie w dźwignię to dropi mi ja i tabliczkę a chce żeby to działało tak że usuwa dźwignię i stawia tabliczkę.

on rightclick on lever:
	loop blocks in radius 1 around event-block:
		if loop-block is redstone wire:
			if difference between now and {%location of event-block%::czas} < 3 seconds:
				add 1 to {%location of event-block%::ilosc}
				if {%location of event-block%::ilosc} = 4:
					set {%location of event-block%::ilosc} to 0
					set event-block to sign
					set line 1 of event-block to "&4Nie baw sie."
					drop 1 of lever at event-block
			else:
				set {%location of event-block%::ilosc} to 0
				set {%location of event-block%::czas} to now
