	trigger:
		open chest with 6 rows named "&8Wybierz kategorię" to player
		set {_x} to 0
		loop 60 times:
			set slot {_x} of player's current inventory to 1 of gray window glass named " "

	if inventory name of player's current inventory is "&8Wybierz kategorię":
		cancel event
		if clicked slot is 11 or 12 or 13 or 14 or 15 or 16 or 17 or 18 or 19 or 20 or 21 or 22 or 23 or 24:
			set {_r} to name of clicked item

			execute console command "shopSELECT %player% %{_r}%"
		else if clicked slot is 53:
			close player's inventory

(prosze nie pisać ,że jest brzydkie, niepoukładane itp. Ma to po prostu działać i działa)   Mam tu taki sktypt, jak można zauważyć jest to zwykłe gui. i mam problem dokładnie z 
 

set {_r} to name of clicked item

działa to, ale tylko na niektóre bloki. Jeżeli kliknę na np. diax kilof wtedy send "%{_r}%" wyświetli mi &7Górnictwo, ale jeżeli klinkę np. na oak log wtedy wyświetli mi <none>. Ktoś może wie czym to jest spowodowane ,że na niektóre działa a na niektóre nie?
