Problem with paste to lua code drop vial

[rozbitekupiee]

Module.New('DropVials', function()
for i = 283, 285 do
if (Self.ItemCount(i) > math.random(6, 9) and Self.TargetID() == 0) then
Self.DropFlasks(Self.Position().x, Self.Position().y, Self.Position().z)
end
end
end)

I need drop vial and I don't know where I can paste this script... to lua I know, where I can paste this script ?
