Previous and forward stage button for obby

[AmericanEagle124579 (C4SE)]

I’ve been trying to make a proper working system for a forwards and backwards gui but so far i have been unsuccessful.
backwards remote script:
Runcontext: Server

game.ReplicatedStorage.back.OnServerEvent:Connect(function(plr)
	
	if plr.back.Value == 0 then
		plr.back.Value = 1
	else
		plr.back.Value = plr.back.Value+1
	end
	
	
	
	
end)

Forwards remote script:

game.ReplicatedStorage.forward.OnServerEvent:Connect(function(plr)
	print("forward passed test")
	plr.back.Value = plr.back.Value-1
end)

Backwards script so far:

local Stages = workspace:WaitForChild("Stages")

script.Parent.MouseButton1Click:Connect(function(plr)
	wait(0.5)
	local playerback = script.Parent.Parent.Parent.Parent.Parent.back.Value
game.ReplicatedStorage.back:FireServer(plr)
	local playerCheckpoint = script.Parent.Parent.Parent.Parent.Parent.leaderstats.Stage.Value
	print(playerCheckpoint)
	if playerCheckpoint > 1 then -- Ensure the player is not on the first checkpoint
		local teleportCheckpoint = game.Workspace.Stages:FindFirstChild(tostring(playerCheckpoint - 1))
		
		print(teleportCheckpoint)
		if teleportCheckpoint then
			script.Parent.Parent.Parent.Parent.Parent.Character.HumanoidRootPart.CFrame = CFrame.new(teleportCheckpoint.Position)+Vector3.new(0,2,0)
		
		end
	end
end)

Forward script so far:

local Stages = workspace:WaitForChild("Stages")
local followmeinmerrymeasure
script.Parent.MouseButton1Click:Connect(function(plr)
	wait(0.5)
	local playerback = script.Parent.Parent.Parent.Parent.Parent.forward.Value
	local playerback2 = script.Parent.Parent.Parent.Parent.Parent.back.Value
	
	local playerCheckpoint = script.Parent.Parent.Parent.Parent.Parent.leaderstats.Stage.Value
	local playerCheckpoint100 = tonumber(script.Parent.Parent.Parent.Parent.Parent.leaderstats.Stage.Value)
	
	
		
			game.ReplicatedStorage.forward:FireServer(plr)
		local targetCheckpoint = Stages:FindFirstChild(tostring(playerCheckpoint-playerback2 + 1))
	followmeinmerrymeasure = tonumber(targetCheckpoint.Name)
	if playerCheckpoint < followmeinmerrymeasure then
		return
	
			else
			if targetCheckpoint then
				script.Parent.Parent.Parent.Parent.Parent.Character.HumanoidRootPart.CFrame = CFrame.new(targetCheckpoint.Position) + Vector3.new(0, 2, 0)
			end
		
	end
end)

if any more information is needed, I am very happy to provide as I want to get this finished.

the first problem i see is the amount of Parents

local playerback = script.Parent.Parent.Parent.Parent.Parent.forward.Value
local playerback2 = script.Parent.Parent.Parent.Parent.Parent.back.Value
	
local playerCheckpoint = script.Parent.Parent.Parent.Parent.Parent.leaderstats.Stage.Value
local playerCheckpoint100 = tonumber(script.Parent.Parent.Parent.Parent.Parent.leaderstats.Stage.Value)

...

local playerCheckpoint = script.Parent.Parent.Parent.Parent.Parent.leaderstats.Stage.Value
local playerback = script.Parent.Parent.Parent.Parent.Parent.back.Value

get the player like this instead

local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()

-- Now you can get the player's stuff properly
local Back = Player:WaitForChild("Back")

also this can be shortened

if plr.back.Value == 0 then
  plr.back.Value = 1
else
  plr.back.Value = plr.back.Value+1
end

-- plr -> Player
-- "if value is 0 then set value to 1 else if value isn't 0 then add 1"
-- just add 1 without checking
Player.Back.Value += 1

I took your suggestion and played around with it a bit and realized that I never specified the name while I was writing the datastore portion of the CurrentStage stat. I had also given you the wrong script as well. I had provided a past local script on accident. Then after realizing in the handler that I never specified the correct path for the player to teleport to, I fixed it up and it worked. Thank you for taking the time out of your day to provide code.
