Why are the leaderstats not being placed?

this is my script; i tried to detect when it hits and stop it from being hit over and over and it keeps doing that. also, the leaderstats don't add, any solution? thanks

	for i, v in pairs(Cloned_Cube.Squares:GetChildren()) do
		local db = false
		v.Touched:Connect(function(hit)
			if hit.Parent:FindFirstChild("Humanoid") and db == false then
				db = true
				local player = game.Players:GetPlayerFromCharacter(hit.Parent)
				if player.TeamColor.Color ~= v.Color then
					local effect = Instance.new("Sound", workspace)
					effect.SoundId = "rbxassetid://5893607560"
					effect.Volume = 0.6
					effect.Playing = true
					v.Color = player.TeamColor.Color
					player.leaderstats.Tiles.Value += 1
					if v.Color ~= Color3.fromRGB(63, 64, 68) and v.Color ~= Color3.fromRGB(202, 203, 209) then
						if v.Color == Color3.fromRGB(4, 175, 236) and player.TeamColor.Color ~= v.Color then -- Blue team
							local player = Blue_Team:GetPlayers()[math.random(1, #Blue_Team:GetPlayers())]
							player.leaderstats.Tiles.Value += -1
						elseif v.Color == Color3.fromRGB(0, 255, 0) and player.TeamColor.Color ~= v.Color then -- Green
							local player = Green_Team:GetPlayers()[math.random(1, #Green_Team:GetPlayers())]
							player.leaderstats.Tiles.Value += -1
						elseif v.Color == Color3.fromRGB(255, 102, 204) and player.TeamColor.Color ~= v.Color then --Pink
							local player = Pink_Team:GetPlayers()[math.random(1, #Pink_Team:GetPlayers())]
							player.leaderstats.Tiles.Value += -1
						end
					end
					wait(0.4)
					effect:Destroy()
					db = false
				end
			end
		end)
