gfx.halloweenfx = “Fred”, is a valid value, but it’s not a display object. You can check to see:

if gfx and gfx.halloweenfx and gfx.halloweenfx.removeSelf then     -- gfx is valid     -- gfx.halloweenfx exists (not nil)     -- gfx.halloweenfx.removeSelf is a display object method, so this is quite likely a display object.     --      -- do something with your display object. end
