I'm making an HD Admin command that gives a person a bubble around themselves, it's not working?

This is the script in ClientCommands:

    ["bubble"] = {
        Function = function(speaker, args)
            local plr = args[1]
            local torso = plr.Torso
            if torso then
                local part = Instance.new("Part", torso)
                part.Shape = Enum.PartType.Ball
                part.Transparency = 0
                part.CanCollide = true
                part.Size = Vector3.new(10.14,10.14,10.14)
                part.Parent = torso.Position
        end
        end;
        };
