Module Script keeps crashing? Thanks for the help.

Module Script (In workspace)

local DataSave = {}
--wait()
--game:WaitForChild("ServerStorage")
----game:WaitForChild("DataStoreService")
game:GetService("DataStoreService")
local SafeStore = game.ServerStorage:FindFirstChild("PlayersData")
local mouse = game.Players.LocalPlayer:GetMouse()

DataSave.ItemTaken = function()
	print(game.Players.LocalPlayer.Name)
	--local mouse = game.Players.LocalPlayer:GetMouse()
	local Player = game.Players.LocalPlayer
	--local PlrData = SafeStore:findFirstChild(Player.userId)
	if mouse.Target ~= nil then
		if mouse.Target:findFirstChild("CanPickUp") then
			if mouse.Target:findFirstChild("CanPickUp").Value == true then
				local Item = mouse.Target:findFirstChild("CanPickUp").Parent
				print(Item.Name .. " Is what your trying to pick up!")
				local found = nil
				local values = Player.Data.SlotHold:GetChildren()
				for i=1,#values do
					if values[i].ClassName == "BoolValue" then
						if values[i].Value == false then
							found = values[i]
							break
						end
					end
				end
				if found ~= nil then
				print(found)
				Player.Data.SlotHold:findFirstChild(found.Name).Value = true
				local CurrentSlot = Player.Data.SlotHold:findFirstChild(found.Slot.Value).Name
				print(Player.Data.SlotHold:findFirstChild(found.Slot.Value).Name .. " Is line 31")
				print(CurrentSlot.Name)
				local SlotTemp = Player.Data.SlotHold:findFirstChild(CurrentSlot)
				print(SlotTemp.Parent)
				SlotTemp.ItemName.Value = (mouse.Target:findFirstChild("CanPickUp").Parent.Name)
				---CurrentSlot.ItemStock.Value = 
				end
				if found == nil then
				print("Invintory Full!")
				end
			end
		end
	end
end
