hello, I'm on version 1.8.9 of my server and I'm trying to use a skript I'm making. basically, I need items to be dropped randomly around the map. to do this, I took the coordinates of each point in the map where I wanted the items to be born, and then through this string I got on skunity "drop 1 stone at location(283,65,201, world "world") without velocity" I put in my coordinates. however, it doesn't work, and it gives me this error
