My script is not working for LocalScript:18: attempt to call a nil value line 18?

local debounce = false
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local character = player.Character or player.CharacterAdded:Wait()
local animInstance = Instance.new("Animation")
local humanoid = character:WaitForChild("Humanoid")
animInstance.AnimationId = "rbxassetid://6380434675"
local anim = humanoid:LoadAnimation(animInstance)
local Col = game:GetService("CollectionService")
local tag = Col:GetTagged("Rain")
local torso = game.Workspace:FindFirstChild(player.Name)
mouse.KeyDown:connect(function(key)
	if key == "e" then
		if not debounce then
			anim:Play()
			for _, TaggedPart in pairs(tag) do
				for count = 1, 5 do
			local part = tag:Clone()
			part.Parent = game.Workspace
			part.Position = torso.UpperTorso.Position +(torso.UpperTorso.CFrame.lookVector*5) + Vector3.new(0,20,0)
			debounce = true
			wait(0.1)
			debounce = false
			end
			end
			end
	end
	end)

You have to say 'TaggedPart'. Like this:

for _, TaggedPart in pairs(tag) do
   for count = 1, 5 do
   local part = TaggedPart:Clone() -- You have to say 'TaggedPart'
   part.Parent = game.Workspace
end

Hope it helps
