I cant use repeats pls help ,Why wont this work?

game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		RaceManager.IntermissionStarted:connect(function()
			
			local intermissionDuration = RaceManager:GetIntermissionDuration()
			
			wait(intermissionDuration / 2)
			pushPlayerName("RACE STARTING SOON", intermissionDuration / 4)
	
			--Random Start Grid Spawn
			local Spawns = workspace.Game.GridLineUp:GetChildren()
			local random = Spawns[math.random(1,#Spawns)]
			
			--Moves the kart if there is a kart in the workspace to the starting grid
			local Class   = game.Workspace.Game.GameSettings.Class.Value
			local Kart = game.Workspace.Game.SpawnedGoKarts:FindFirstChild(player.Name.."'s "..Class)
			
			repeat
				for i = 1, #Spawns do
					if Spawns[i]:FindFirstChild("Occupied").Value == false then do
						warn("NOT OCCUPIED M8")
						if (Kart) then 
							Kart:SetPrimaryPartCFrame(random.CFrame + Vector3.new(0,3,1))
							warn(player.Name.."'s " ..Class.." has been Moved to a starting grid")
						else
							warn("Occupide")
						end
					end
					end
				end
			until not Spawns[i]:FindFirstChild("Occupied").Value == false
		end)
		end)
		end)
		
	end)
end)
end)

I cant use ends it seems like ;/

Basically i want it to keep searching for a free spawn place until its found, as when someone spawns there (Occupide) will be true. Like in a racing game telling the script that the player cannot spawn there with the kart.
