This has no error, and its in a GUI but the wait(function() end) will not respond.

local DS=game:GetService("DataStoreService"):GetDataStore("AnsweredCorrect") 
print'got DS'

function DATA_Service_UPDATE()
local plr=script.Parent.Parent.Parent
	 
	local key = 'user_'..plr.userId
	print'got key'
	
	wait(function() -- This doesnt respond, but it doesnt error. :/ Im not sure what the error is.
	-- Any idea?
	DS:UpdateAsync(key, function(oldValue)
		 print'Updated Ansy()'
		local newValue = oldValue or 0 print'oldValue or 0'
		
			newValue = game.Players[plr.Name]['leaderstats']['Correct Guess\'s & Credits'].Value
						
						print'leaderstats + 0'
						
					game.Players[plr.Name]['leaderstats']['Correct Guess\'s & Credits'].Value=(newValue)
					
					print'added stats'
				print(newValue)
				
			return newValue
		end)
	print'returned oldValue or 0'
	end)
end
