Help with events

EVENT_SAY isn't triggered as a player quest event, so that code will never execute. Probably the easiest way to do what you want is to create an invisible npc in the area that you want to use.
Then, in that npc's script, create a proximity for the area you want the player to be in and use the EVENT_PROXIMITY_SAY event to trigger when someone says that text without needing to target the npc.
