A bunch of my values are nan

I’ve researched how a value becomes nan and its if it becomes equal to 0/0.

The problem is, I have done nothing with my level value and it is profileservice value. I made some changes before to make a leveling system which I previously failed in but I am back to fix it.

I don’t want to make an if statement setting the players level to 1 to fix nan just because it will appear as nan in leveling gui for 1 round.

if level == 0/0 then
	PlayerData:Set(player,"Level",1)
end

local function InPlayers(signal,par1,par2)
	if signal == "Gain" then
		local xp = par2:GetAttribute("RoundExperience")
		par2:SetAttribute("RoundExperience",xp + par1)
		return
	end
	for _,player in Players:GetPlayers() do
		if signal == "Start" then
			player:SetAttribute("RoundExperience",0)
		elseif signal == "Receive" then
			local experience = PlayerData:Get(player,"Experience")
			local level = PlayerData:Get(player,"Level")
			local progress = experience / (300 * level)
			local new
			if level == 0/0 then
				PlayerData:Set(player,"Level",1)
			end
			if progress >= 1 then
				new = math.abs(progress - level)
				PlayerData:Set(player,"Level",level + 1)
				PlayerData:Set(player,"Experience",progress)
			end
			print(experience,level,progress)
			Remotes.ToClient:FireClient(player,"LoadXP",experience,level,new)
			player:SetAttribute("Experience",nil)
		end
	end
end

This is the function I am using for my leveling system on the server.

Remotes.ToClient.OnClientEvent:Connect(function(signal,experience,level,progress)
	if signal == "LoadXP" then
		task.spawn(function()
			LevelGui.Enabled = true
			task.wait(5)
			if LevelGui.Enabled then
				LevelLabel.Text = ""
				ExperienceLabel.Text = ""
				Experience.Size = UDim2.fromScale(0,1)
				LevelGui.Enabled = false
			end
		end)
		LevelLabel.Text = "Level: " .. tostring(level)
		ExperienceLabel.Text = "+"..tostring(experience).. " Experience!"
		if experience > 0 then
			TweenService:Create(Experience,TweenInfo.new(0.75,Enum.EasingStyle.Sine,Enum.EasingDirection.Out),{Size = UDim2.fromScale(progress,1)}):Play()
		end
	end
end)

This is the code handling the gui on the client.

I’m using a certain formula to track progress which is (experience / (300 * level)) but it hasn’t shown to work for me. I tried using temporary experience which would still save but be reset after you change a level(I was making players have permanent experience).

Make sure your experience and levels are never 0. If experience is 0, and level is 0, your progress will be NaN. As far as I can tell thats the only place where NaN is possible.

Well the level is supposed to be 1, and the experience is supposed to be 0 at the very beginning.

I would try to reset my data(using profileservice) to restart and see if something I did previously ruined the experience and level key connected my player. I just don’t know how I would do that without a plugin.
