FPS/TPS script working fine in solo, yet not in the game? HELP!

I fixed the script! It works perfectly the way it should! Since the whole script is open source, here is the link to the model: http://www.roblox.com/FPS-TPS-Script-item?id=302280310

Or you can have the code (LocalScript in StarterPack):

local ToggleKey = "t"
local Player = game.Players.LocalPlayer
Player.CameraMode = Enum.CameraMode.LockFirstPerson
local Character = Player.Character or Player.CharacterAdded:wait()
wait(2.5)
local Mouse = Player:GetMouse()
local Camera = game.Workspace.CurrentCamera

local AM = Instance.new("Model", Camera)
local FakeParts = {}
AM.Name = "TPSBody"
Arms = {Player.Character["Left Arm"], Player.Character["Right Arm"]}
Arm1 = Instance.new("Part", AM)
Arm1.Name = "Left Arm"
Arm1.CanCollide = false
Arm1.FormFactor = Enum.FormFactor.Custom
Arm1.Size = Arms[1].Size - Vector3.new(0.1, 0.1, 0.1)
Arm1.BrickColor = Arms[1].BrickColor
table.insert(FakeParts, #FakeParts+1, Arm1)
Arm2 = Instance.new("Part", AM)
Arm2.Name = "Right Arm"
Arm2.CanCollide = false
Arm2.FormFactor = Enum.FormFactor.Custom
Arm2.Size = Arms[2].Size - Vector3.new(0.1, 0.1, 0.1)
Arm2.BrickColor = Arms[2].BrickColor
table.insert(FakeParts, #FakeParts+1, Arm2)
W1 = Instance.new("Weld", Arm1)
W1.Part0 = Arms[1]
W1.Part1 = Arm1
W2 = Instance.new("Weld", Arm2)
W2.Part0 = Arms[2]
W2.Part1 = Arm2
Legs = {Player.Character["Left Leg"], Player.Character["Right Leg"]}
Leg1 = Instance.new("Part", AM)
Leg1.Name = "Left Leg"
Leg1.CanCollide = false
Leg1.FormFactor = Enum.FormFactor.Custom
Leg1.Size = Legs[1].Size
Leg1.BrickColor = Legs[1].BrickColor
table.insert(FakeParts, #FakeParts+1, Leg1)

Leg2.Name = "Right Leg"
Leg2.CanCollide = false
Leg2.FormFactor = Enum.FormFactor.Custom

table.insert(FakeParts, #FakeParts+1, Head)

for _,Obj in pairs(Player.Character:GetChildren()) do

        Obj:Clone().Parent = AM
    end
    if Obj:IsA("Hat") then
        local NewHat = Obj:Clone()
        NewHat.Parent = AM
        table.insert(FakeParts, #FakeParts+1, NewHat.Handle)
        wait()

    end
    wait()
end

Character.Humanoid.Died:connect(function()
    AM:Destroy()
    Character.Humanoid.CameraOffset = Vector3.new(0, 0, 0)
    connect:disconnect()
end)

for i,v in pairs(FakeParts) do
    v.Transparency = 1
end

print("Connecting the mouse...")

connect = Mouse.KeyDown:connect(function(key)
    if key == ToggleKey then
        if Character.Humanoid.CameraOffset == Vector3.new(0, 0, 0) then
            Character.Humanoid.CameraOffset = Vector3.new(1.5, 0.5, 5)
            for i,v in pairs(FakeParts) do
                v.Transparency = 0
            end
        elseif Character.Humanoid.CameraOffset == Vector3.new(1.5, 0.5, 5) then
            Character.Humanoid.CameraOffset = Vector3.new(0, 0, 0)
            for i,v in pairs(FakeParts) do
                v.Transparency = 1
            end
        end
    end
end)

Thanks for the help guys!
