I want the player's clothes to be changed through a Remote Event, But it Dont work?

Hi, I want the player's clothes to be changed through a Remote Event, so I can enable the FE in my game. But it doesn't work, it doesn't give error or warnings or anything, it just doesn't work. Look at my scripts:

Local script

        local PantsId = script.Parent.Parent:FindFirstChild("").Pants.PantsTemplate
local ShirtId = script.Parent.Parent:FindFirstChild("").Shirt.ShirtTemplate

script.Parent.Bottom.ClickDetector.MouseClick:connect(function(player)
        game.ReplicatedStorage.Changer:FireServer(PantsId, "p")
end)
script.Parent.Top.ClickDetector.MouseClick:connect(function(player)
        game.ReplicatedStorage.Changer:FireServer(ShirtId, "s")
end)

Server script

game.ReplicatedStorage.Changer.OnServerEvent:Connect(function(p,Id, PS)
if PS == "p" then
        p.Character.Pants.PantsTemplate = Id
elseif PS == "s" then

        p.Character.Shirt.ShirtTemplate = Id
end
end)

If there is another simpler way to change the player's clothes and everyone else can see with the FE enabled, please tell me.
