These scripts work only in the studio, not in the actual game, any solutions?

Here's the local script:

script.Parent.MouseButton1Click:Connect(function()


    workspace.Events.h1:FireServer()


end)

Here's the server script:

wait()
script.Parent.OnServerEvent:Connect(function(player)

    player.Character.Head.h:Destroy()

        wait()

    local h1 = game.ReplicatedStorage.Hairs.h1:Clone()
    h1.Name = "h"
    h1.Parent = player.Character.Head

    local weld = Instance.new("Weld")
    weld.Parent = h1
    weld.Part0 = player.Character.Head
    weld.Part1 = h1
    weld.C0 = CFrame.new(0,0,0)
    weld.C1 = CFrame.new(0,-0.5,0)



end)
