Keeps crashing when using script? Is it something to do with loops in if then?

Everytime I touch the part it's supposed to make my player say something, the saying something thing works but it doesn't stop so I tried making it so once h == 9 then it stops repeating. I know it has to do with something having a loop inside of something. Can someone help? Here's the problematic code

					part.Touched:Connect(function(touch)
						if touch.Parent == player.Character then
							repeat 
								h -= 1
	ChatService:Chat(player.Character, "hi",Enum.ChatColor.White)
         until h == 9
  end  
end)
