this is part of my db but you can see most of it umm I am not really a pro at emu stuff only minor things I know how to do so with adding arrows I am pulling a blank big time I am pretty sure I need to add action_spots into my db if that is correct please let me know, and if you have a arrow code that I don't need to add the action_spots that would be better
