Why doesn't my RemoteEvent work?

I made a script that calls a RemoteEvent to determine what you are playing as. I put a value in the player's backpack so if it equals something you play as that character. But for some reason my RemoteEvent isn't working. Here is the script for calling the RemoteEvent.

    if Class.Value == 1 or
        Class.Value == 0 then
        game.Lightning.TestCharacter1.RemoteEvent:FireServer()
    end

and here is the script for the RemoteEvent

local player = game.Players.LocalPlayer
Folder = script.Parent
Event = Folder.IsChar1


script.Parent.RemoteEvent.OnServerEvent:connect(function()
                player.Character.LowerTorso.Transparency = 0

                    wait(0.01)

            player.Character.Head.face.Texture = "http://www.roblox.com/asset/?id=591414447"

    local Sleeve = Instance.new("Part", player.Character)
    Sleeve.CanCollide = false
    Sleeve.Anchored = false
    Sleeve.BrickColor = BrickColor.new("Maroon")
     Sleeve.Size = Vector3.new(1.11, 1.2, 1.07)
    local w = Instance.new("Weld", Sleeve)
    w.Part0 = player.Character.RightUpperArm
    w.Part1 = Sleeve
    w.C1 = CFrame.new(0,-0.36,0)

    local Sleeve2 = Instance.new("Part", player.Character)
    Sleeve2.CanCollide = false
    Sleeve2.Anchored = false
    Sleeve2.BrickColor = BrickColor.new("Maroon")
     Sleeve2.Size = Vector3.new(1.11, 1.2, 1.07)
    local w = Instance.new("Weld", Sleeve)
    w.Part0 = player.Character.LeftUpperArm
    w.Part1 = Sleeve2
    w.C1 = CFrame.new(0,-0.36,0)

    local Tanktop = game.ReplicatedStorage.Union:Clone()
            Tanktop.Parent = player.Character
         local w = Instance.new("Weld", Sleeve)
        w.Part0 = player.Character.UpperTorso
        w.Part1 = Tanktop
        w.C1 = CFrame.new(0,0.18,0)

            local UpPant = Instance.new("Part", player.Character)
        UpPant.CanCollide = false
        UpPant.Anchored = false
        UpPant.BrickColor = BrickColor.new("Really black")
        UpPant.Size = Vector3.new(1.08, 1.21,1.04)
            local w = Instance.new("Weld", player.Character)
        w.Part0 = player.Character.LeftUpperLeg
        w.Part1 = UpPant
        w.C0 = CFrame.new(0,0.25,0)

            local UpPant2 = Instance.new("Part", player.Character)
        UpPant2.CanCollide = false
        UpPant2.Anchored = false
        UpPant2.BrickColor = BrickColor.new("Really black")
        UpPant2.Size = Vector3.new(1.08, 1.29,1.04)
            local w = Instance.new("Weld", player.Character)
        w.Part0 = player.Character.RightUpperLeg
        w.Part1 = UpPant2
        w.C0 = CFrame.new(0,0.15,0)

        local LowPant = Instance.new("Part", player.Character)
        LowPant.CanCollide = false
        LowPant.Anchored = false
        LowPant.BrickColor = BrickColor.new("Really black")
        LowPant.Size = Vector3.new(1.08, 1.23,1.04)
            local w = Instance.new("Weld", player.Character)
        w.Part0 = player.Character.RightLowerLeg
        w.Part1 = LowPant
        w.C0 = CFrame.new(0,0,0)

        local LowPant1 = Instance.new("Part", player.Character)
        LowPant1.CanCollide = false
        LowPant1.Anchored = false
        LowPant1.BrickColor = BrickColor.new("Really black")
        LowPant1.Size = Vector3.new(1.08, 1.21,1.04)
            local w = Instance.new("Weld", player.Character)
        w.Part0 = player.Character.LeftLowerLeg
        w.Part1 = LowPant1
        w.C0 = CFrame.new(0,0,0)

end)

print("works")

^ is suppose to tell me if every part is welded to the player.
