return SpecialSlot

This is one of my widgets.

 

AddClassPostConstruct("widgets/inventorybar", function(self)
	local SpecialSlot = require "widgets/specialslot"
	
	self.special_slots = {}
	
	function self:GetSpecialSlot(slotkey)
		if self.special_slots[slotkey] then
			return self.special_slots[slotkey].inst
		end
	end
	
	function self:AddSpecialSlot(slotkey, owner)
		self.special_slots[slotkey] = {inst = self.toprow:AddChild(SpecialSlot(HUD_ATLAS, "inv_slot.tex", owner)), owner = owner }

		--self.special_slot = self.toprow:AddChild(SpecialSlot(HUD_ATLAS, "inv_slot.tex", self.owner))
		local pos = self.equip[EQUIPSLOTS.HANDS]:GetPosition()

		self.special_slots[slotkey].inst:SetPosition(pos.x, pos.y + 95, pos.z)
		self.special_slots[slotkey].inst:MoveToBack()
	end
	
	function self:SetSpecialSlotFn(slotkey, clickfn, oncontrolfn, onitemgetfn, onitemlosefn)
		if not self.special_slots[slotkey] then
			print ("ERROR! TRYING TO SET UP A NON EXISTENT SPECIAL SLOT")
			return
		end

		self.special_slots[slotkey].clickfn = clickfn
		self.special_slots[slotkey].inst.clickfn = clickfn

		self.special_slots[slotkey].oncontrolfn = oncontrolfn
		self.special_slots[slotkey].inst.oncontrolfn = oncontrolfn

		self.special_slots[slotkey].onitemgetfn = onitemgetfn
		self.special_slots[slotkey].inst.onitemgetfn = onitemgetfn

		self.special_slots[slotkey].onitemlosefn = onitemlosefn
		self.special_slots[slotkey].inst.onitemlosefn = onitemlosefn
	end
end)

And this is the Classpostconstruct I have, my pew matic horn calls the AddSpecialSlot but then crashes because the assertion failed.

Thanks for reading!

Literally just figured this out minutes after I posted this, @ImDaMisterL Feel free to delete/hide this.
