Why won't the character look the same on another screen? FilteringEnabled is on.

local player = game.Players.LocalPlayer
local color = BrickColor.new('Pastel brown')

script.Parent.MouseButton1Down:connect(function()
    if player.Character then
        for i,v in pairs(player.Character:GetChildren()) do
            if v:IsA('BasePart') then v.BrickColor = color end
        end
    end
end)

local player = game.Players.LocalPlayer


script.Parent.MouseButton1Down:connect(function()

if player.Character:findFirstChild("Shirt") then
player.Character.Shirt.ShirtTemplate="http://www.roblox.com/asset/?id=202704957"
else
local s = Instance.new("Shirt", player.Character)
s.ShirtTemplate="http://www.roblox.com/asset/?id=202704957"
end

if player.Character:findFirstChild("Pants") then
player.Character.Pants.PantsTemplate="http://www.roblox.com/asset/?id=204058688"
else
local p = Instance.new("Pants", player.Character)
player.Character.Pants.PantsTemplate="http://www.roblox.com/asset/?id=204058688"
end

end)

FilteringEnabled is on. The point of this script is to change the appearance of a player. That works but one small problem. The players shirt and pants change but only on the players computer. So player2 or another person playing can only see their skin color change but the pants and the shirt would not change. I am sorry but this is really hard to explain.
