attempt to index nil with 'Character'?

I keep getting the error 'Attempt to index nil with 'Character'. Here's the code:

local CMouse = require(script.CMouse)
while CMouse:GetPlayer() == nil do
    game:GetService("RunService").Stepped:wait()
end
UserInputService = game:GetService("UserInputService") --For left mouse click and others
local Player2 = game.Players.LocalPlayer
local mouse = CMouse
local db = true
local damaged = false

local PunchAnim = Instance.new("Animation")
PunchAnim.AnimationId = ""
Players = game:GetService("Players")
plr = CMouse:GetPlayer() --getting all of the body parts. (R6)
char = plr.Character or plr.CharactedAdded:wait()
hum = char:FindFirstChildOfClass'Humanoid'
local cam = game.Workspace.CurrentCamera --Getting the camera
Camera = cam
cam.CameraType = "Custom"
t = char.Torso
h = char.Head
ra = char["Right Arm"]
la = char["Left Arm"]
rl = char["Right Leg"]
ll = char["Left Leg"]
tors = char:WaitForChild("Torso")
lleg = char["Left Leg"]
root = char.HumanoidRootPart
hed = char.Head
rleg = char["Right Leg"]
rarm = char["Right Arm"]
larm = char["Left Arm"]
print(Players, plr, char, hum, cam, Camera, t, h, ra, la, rl, ll, tors, lleg, root, hed, rleg, rarm, larm, mouse) --Prints all of the stuff

game.Players.LocalPlayer.Character:FindFirstChild("Right Arm").Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") and not db and not damaged and hit.Parent.Humanoid ~= game.Players.LocalPlayer.Character.Humanoid then
        damaged = true
        script.Punch:FireServer(hit.Parent.Humanoid)
    end
end)

UserInputService.InputBegan:Connect(function(input, event)
    if input.KeyCode == Enum.UserInputType.MouseButton1 then
        print("punch")
    end
end)

I am trying to make a punch action for my glitcher, it is FE and i cant solve this, can some people help me? Please and thank you!
