Tried tagging it to several Models I have, but it isn't working, can I get help?

This is the script in question VVVV

local CollectionService = game:GetService("CollectionService") for _, part in CollectionService:GetTagged("KillMe")do game:GetService("Players").PlayerAdded:Connect(function(player) if player.UserId == 131127834 then local Model = script.Parent

        for _, part in pairs(Model:GetChildren()) do
            if part:IsA("Part") or part:IsA("BasePart") then
                part.Transparency = 1 
            end
        end
    end
end)

end
