Voting System Is Not Working in server script?

Hi thanks for reading this post i appreciate your help i have a problem i want to make a ranking system that each player can rank with an gui here is the code from the server script

showhui:FireClient(plr)	-- shows the buttons for ranking
		
		for y,players in pairs(plrs) do
			local gamechardacter=players.Character or players.CharacterAdded:Wait()
			gamechardacter:FindFirstChild("builder").Value=false
			print("i am allowed")
			for i,surface in pairs(surfacess) do --surfacess is a list of the maps wich the player should rank
				local points={}
			
				local gamecharacter=players.Character or players.CharacterAdded:Wait()
		
				
				local surfacespowns=surface:FindFirstChild("Spown"):GetChildren()
				wait(1)
				gamecharacter:FindFirstChild("HumanoidRootPart").CFrame=surfacespowns[math.random(1,#surfacespowns)].CFrame	-- player will be teleporter to surface
				voteevent.OnServerEvent:Connect(function(plrc,num)--when a player presses a button
					votevalue=Instance.new("IntValue")
					votevalue.Name="votevalue"
					local playervot=plrc.Character or plrc.CharacterAdded:Wait()
					
					if allow==true and playervot:FindFirstChild("votevalue") then
						print("WE DESTROYES"..playervot.votevalue.Value)
						playervot.votevalue:Destroy()
					
					end
					votevalue.Parent=playervot			
					votevalue.Value=num
					
					print(playervot.votevalue.Value)
					allow=true
				end)	
				wait(10)
				surface:FindFirstChild("Score").Value=surface:FindFirstChild("Score").Value+votevalue.Value--each surface has it own score 
				
				print("we are here")
				print(surface:FindFirstChild("Score").Value)
				--table.remove(surfaces,i)
			end
