the code

Client

game.ReplicatedStorage.Teleport.OnClientEvent:Connect(function(Player, Level)
	
	local leaderstats = Player:WaitForChild("leaderstats")
	
	if leaderstats.Level.Value >= Level then
		
		leaderstats.Level.Value += 1
	end
end)

Server

local TeleportEvent = game.ReplicatedStorage.Teleport
	
	local Part = script.Parent
	
local Teleport = Part.Teleport.Value
	
	local Level = Teleport:GetAttribute("Level")

Part.Touched:Connect(function(hit) 
		
		if hit.Parent:FindFirstChild("Humanoid") then 
			
			if game:GetService("Players"):FindFirstChild(hit.Parent.Name) then 
				
				local Player = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
	
				TeleportEvent:FireClient(Player, Level)
				
				task.wait(1)
				
				game:GetService("Players"):GetPlayerFromCharacter(hit.Parent).Character:WaitForChild("HumanoidRootPart").CFrame = Teleport.CFrame
			end
		end
	end)

FireClient doesn’t send the player as argument to OnClientEvent, you need to add the player as an argument, e.g.

TeleportEvent:FireClient(Player, Player, Level)

You changed this TeleportEvent:FireClient(Player, Level) to this TeleportEvent:FireClient(Player, Player, Level)?

And second error is telling that you are trying to compare nil with number and this is probably because Level is nil

Always use Players.LocalPlayer in local scripts when you want to get a reference to local player.
The second error means that Teleport does not have an attribute named “Level”.

(And don’t put vertical whitespaces after every line, it is hurting readability)

Please don’t try to get player like this. Use the method that I described above.

I know that using LocalPlayer will be better, but I wanted answer to why this specific error happened

You didn’t answer why this specific error happened. What you did is you said to send additional player argument, which is a bad practice.

It does not send the first player argument as a parameter to OnClientEvent. Anyways, you could have just said to use Players.LocalPlayer.
