Why is my function returning nil?

I have this function that loops through a folder that hold the players turn order via string values named 'Player1', 'Player2', 'Player3',etc. all the way up to 'Player8'. If the value is empty then the value is removed via a different script. but thats not the issue. Whenever i check for the players name then return the players name and attempt to print the function i get the error ServerStorage.doTurn:31: attempt to concatenate a nil value

This is the function:

local RS = game:GetService("ReplicatedStorage")
local TurnNum = RS.Turn

local function getPlayerTurn()
	for i,v in pairs(RS.PlayerOrder:GetChildren()) do
		print(TurnNum.Value)
		if v.Name == 'Player'.. tostring(TurnNum.Value) then
			print(v.Name)
			return v.Name
		else
			TurnNum.Value = TurnNum.Value + 1
			wait()
			getPlayerTurn()
		end
	end
end

print(getPlayerTurn().."'s turn")

EDIT: TurnNum gets set to 1 when it reaches 9(making it range from 1 - 8)

So Im not completely sure but try

local RS = game:GetService("ReplicatedStorage") local TurnNum = RS.Turn

local Name
local function getPlayerTurn()
	for i,v in pairs(RS.PlayerOrder:GetChildren()) do
		print(TurnNum.Value)
		if v.Name == 'Player'.. tostring(TurnNum.Value) then
			print(v.Name)
			Name = v.Name
		else
			TurnNum.Value = TurnNum.Value + 1
			wait()
			getPlayerTurn()
		end
	end
	return Name
end

print(getPlayerTurn().."'s turn")

making the name a value but as previously stated i'm not completely sure
