Error When Making Checkpoint System

Hey everyone, it’s me again! :smiley:

I’ve been trying to make a checkpoint system, and after following a tutorial, I can up with this code:

game.Players.PlayerAdded:Connect(function(player)
	
	local leaderstats = Instance.new("Folder")
	leaderstats.Parent = player
	leaderstats.Name = "leaderstats"
	
	local Level = Instance.new("IntValue")
	Level.Parent = leaderstats
	Level.Name = "Level"
	Level.Value = 1
	player.CharacterAdded:Connect(function(character)
		wait()
		local checkpoint = game.Workspace.Checkpoints:FindFirstChild("Checkpoint" .. Level.Value)
	end)
end)

for i, v in pairs (game.Workspace.Checkpoints:GetChildren()) do
	v.Touched:Connect(function(hit)
		local player = game.Players:GetPlayerFromCharacter(hit.Parent)
		if player then
			local Level = player.leaderstats.Level
			local CheckpointNumber = tonumber(string.sub(v.name, 11, #v.name))
			if CheckpointNumber > Level then
				Level.Value = CheckpointNumber
			end
		end
	end)
end

However, it keeps giving me an error on line 23 (if CheckpointNumber > Level then), saying that I cannot compare a number to an Instance. There doesn’t seem to be an error on the tutorial, did I do something wrong?

Any help is appreciated, thank you for your time! :smiley:

You need a .Value when trying to get the value of anything

game.Players.PlayerAdded:Connect(function(player)
	
	local leaderstats = Instance.new("Folder")
	leaderstats.Parent = player
	leaderstats.Name = "leaderstats"
	
	local Level = Instance.new("IntValue")
	Level.Parent = leaderstats
	Level.Name = "Level"
	Level.Value = 1
	player.CharacterAdded:Connect(function(character)
		wait()
		local checkpoint = game.Workspace.Checkpoints:FindFirstChild("Checkpoint" .. Level.Value)
	end)
end)

for i, v in pairs (game.Workspace.Checkpoints:GetChildren()) do
	v.Touched:Connect(function(hit)
		local player = game.Players:GetPlayerFromCharacter(hit.Parent)
		if player then
			local Level = player.leaderstats.Level.Value
			local CheckpointNumber = tonumber(string.sub(v.name, 11, #v.name))
			if CheckpointNumber > Level then
				Level.Value = CheckpointNumber
			end
		end
	end)
end

^^ Should work

It solved one problem I guess, but now its giving me an error for trying to index a number with a value on line 24

Thts because u referenced value once again after declaring it. Heres wt I mean:

local Level = player.leaderstats.Level.Value --here u declared .Value
			local CheckpointNumber = tonumber(string.sub(v.name, 11, #v.name))
			if CheckpointNumber > Level then
				Level.Value = CheckpointNumber -- u declared .Value again

Replace it with this

local Level = player.leaderstats.Level
			local CheckpointNumber = tonumber(string.sub(v.name, 11, #v.name))
			if CheckpointNumber > Level.Value then
				Level.Value = CheckpointNumber
5 
local players = game:GetService("Players")
local checkpoints = workspace:WaitForChild("Checkpoints")

players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Parent = player
	leaderstats.Name = "leaderstats"
	local Level = Instance.new("IntValue")
	Level.Parent = leaderstats
	Level.Name = "Level"
	Level.Value = 1
	player.CharacterAdded:Connect(function(character)
		local checkpoint = checkpoints:FindFirstChild("Checkpoint" .. Level.Value)
	end)
end)

for i, v in ipairs(checkpoints:GetChildren()) do
	if v:IsA("BasePart") then
		v.Touched:Connect(function(hit)
			if hit:FindFirstChild("Humanoid") then
				local char = hit.Parent
				local plr = players:GetPlayerFromCharacter(char)
				local leaderstats = plr:WaitForChild("leaderstats")
				local level = leaderstats:WaitForChild("Level")
				local CheckpointNumber = tonumber(string.sub(v.Name, 11, #v.Name))
				if CheckpointNumber > level.Value then
					level.Value = CheckpointNumber
				end
			end
		end)
	end
end

In what format are the checkpoints named?
