W003 Error: I've tried the documented ways

#1

Output:

W003: (76,24) Global 'CreatedSlots' is only used in the enclosing function 'Main'; consider changing it to local

Code:

	local FindOpenSlot = function(Tool)

		for _,VSlot in pairs(CreatedSlots) do
			if VSlot.Tool~=nil and VSlot.Tool == Tool then
				return
			end
		end

		for _,Slot in pairs(CreatedSlots) do 
			if Slot.Tool == nil then
				return Slot
			end
		end
		return CreateExtendedSlot()
		
	end

I’m pretty confused, anyone know how to solve this?

#2

The code you posted has no flaws or errors.
The problem is with the variable “CreatedSlots”.
Show that code.

#3

This is the part that shows an error:

local FindOpenSlot = function(Tool)

		for _,VSlot in pairs(CreatedSlots) do
			if VSlot.Tool~=nil and VSlot.Tool == Tool then
				return
			end
		end

		for _,Slot in pairs(CreatedSlots) do 
			if Slot.Tool == nil then
				return Slot
			end
		end
		return CreateExtendedSlot()
		
	end

	local FindSlotFromUI = function(Frame)
		for _,Slot in pairs(CreatedSlots) do
			if Slot.UI and Slot.UI == Frame then
				return Slot
			end
		end
		return nil
	end

Output:

W003: (76,24) Global 'CreatedSlots' is only used in the enclosing function 'Main'; consider changing it to local

W003: (87,10) Global 'CreateExtendedSlot' is only used in the enclosing function 'Main'; consider changing it to local

CreatedSlots does not have any variables.

#4

for _,VSlot in pairs(CreatedSlots) do

The variable CreatedSlots must be created to function.
You are creating it globally, not locally.

#5

your tables and functions seem to be in scope of another function, that is the reason behind the errors I believe
