Why doesn't this script work in-game[Solved]?

The script seems to be fine and works in Play-Solo but when I tested it in-game it doesn't seem work so I clicked f9 and check the error message which says "Players.UserOnly16Characters.PlayerGui.ScreenGui.Frame.ImageButton.Cloth:6: attempt to index upvalue 'Me' (a nil Value). I don't know why the error only came up in-game and not in Studio?!? D:

local Player = game.Players.LocalPlayer
local Me = Player.Character

script.Parent.MouseButton1Click:connect(function()

local Humanoid = Me:FindFirstChild("Humanoid")
 if Humanoid then

for i,v in pairs (Me:GetChildren()) do
 if v:IsA("Pants") or v:IsA("Shirt") or v:IsA("CharacterMesh") or v:IsA("Hat") then
	v:remove()
end

if v:IsA("Part") then
	v.BrickColor = BrickColor.new("Mid gray")
end end 

print("Recoloured Part and Removed Junk")

for i,v in pairs (Me.Head:GetChildren()) do
if v:IsA("Decal") then
   v:remove()
end end

print("Remove Face Decal")

local A = Instance.new("Shirt", Me)
A.Name = "Shirt"
