Player is not a valid member of ObjectValue?

I understand that it is not a valid member but it's an if then statement Line 37

Part=workspace.DanceClub.Interactions.Queue
Queue=game.ServerScriptService.DanceClub.Values.Queue

Players=Queue:GetChildren()
b=nil
current=0

function Update(new)
	b=new.Name
Players=Queue:GetChildren()
	
	
if #Players > current then
       current=#Players
	for i,v in next ,Players do
		local Gui=game.Players[v].PlayerGui.DDR.Queue
		Gui:GetChildren()
---WIP----		
	end end
if #Players < current then
	current=#Players
	for i,v in pairs(Players) do
		local Gui=game.Players[v].PlayerGui.DDR.Queue
		local re=Gui:findFirstChild(""..b)
		re.Parent:remove()
		
			for i,v in next(Gui) do
			if v:IsA("Frame") then
				if v.Position.Y.Scale>0 then
					v.Position=UDim2.new(0,0,v.Position.Y.Scale-0.13,0)
				
	end end end end end
