I create enchant system with GUI inventory.
But under code don't work...

Code (Text):

1. variables:
2.   {enchant_type::sh} = "sharpness"
3.   {enchant_type::ef} = "efficiency"
4.  
5. on inventory click:
6.   if inventory name of player's current inventory contains "&r&b%player%&r's Upgrade Table":
7.     if clicked slot's type is nether star:
8.       set {_target} to slot 10 of player's current inventory
9.       set {_stonez} to slot 13 of player's current inventory
10.       # slot 13 is stone have lore format ex) "sh 5" / "ef 7"
11.  
12.       set {_split::*} to uncoloured line 1 of {_stonez}'s lore split at " "
13.  
14.       set {_enchant_type} to {_split::1}
15.  
16.  
17.       set {_chkenc} to {enchant_type::%{_enchant_type}%} parsed as enchantment
18.       set {_level} to level of {_chkenc} of {_target}
19.  
20.       message "lv : %{_level}%" to player

result is always <none>
how can I fix this problem?
