大佬帮忙看看哪里出错了

2x !Pig\ShowPlus\ShowPlus.lua:340: attempt to index field '?' (a nil value)
[string "@!Pig\ShowPlus\ShowPlus.lua"]:340: in function <!Pig\ShowPlus\ShowPlus.lua:337>
[string "@!Pig\ShowPlus\ShowPlus.lua"]:426: in function <!Pig\ShowPlus\ShowPlus.lua:414>

Locals:
(for index) = 2
(for limit) = 20
(for step) = 1
inv = 2
(*temporary) = nil
(*temporary) = "InspectHeadSlot"
(*temporary) = "Head"
(*temporary) = "Slot"
(*temporary) = "attempt to index field '?' (a nil value)"
