It works in Studio, but doesn't work Online? [closed]

I don't know what I'm doing wrong. It works flawlessly in Studio, but doesn't do anything (let alone printing a string) while Online.

What I'm trying to accomplish is if the script finds a model with a folder named "Appearance," it'll change the model's parts' brickcolor to the value of the brickcolorvalue (Appearance.SkinColor.Value)

I'm trying to experiment with things, so the following code may look weird to some.

Document = game.ReplicatedStorage:FindFirstChild("Doc")
Camera = workspace.CurrentCamera

while wait(.5) do -- "refresh" every .5 seconds
    for index, value in pairs(Camera:GetChildren()) do
        if value:IsA("Model") then
            local Appearance = value:findFirstChild("Appearance")
            if Appearance then
                print'a'
                for index, skin in pairs(value:GetChildren()) do
                    if skin:IsA("Part") then
                        skin.BrickColor = Appearance.SkinColor.Value
                    end
                end
            elseif not Appearance then
                print'o'
            end
        end
    end
end
