Not sure if this is posted in the right part if its not im sorry 
im wondering if anyone would know how to make it that you can only sell drugs in a certain part of the city for instance you can only sell drugs to npc’s in [ davis/grovestreet, chamberlin hills, rancho, davis/roy lowenstein blvd] or is it possible to set it up that its like a box so put in 4 different coordinates and you can only sell inside that so it would be like a box? the script i use is [Release]drugs to npc's [ESX] i know its possible to do because it was on a server i used to play on but my head is melted trying to do it i cant figure it out
