getService Chat not working with npc?

while true do
wait(3)
game:GetService("Chat"):Chat(script.Parent,"Edit me","Red")

end

When the game runs, Text above npc dosent appear, help?

If the NPC has a hat, you want to make sure this is in the hat, or that you navigate to said hat. If it is just a facial accessory, put this in the head or navigate to its head.

-- NOTE: THIS COUNTS FOR HAIR. --

Also, you might be putting the script into the model, because I've done that before.

-- MAKE SURE IT IS IN THE TOP PART OF THE NPC! --
