Custom player list not working? Need help ASAP.

So basically, I've been trying to make this custom playerlist but for whatever reason, it doesn't work. Here is the script. Help would be great.

wait(.1)
Main = script.Parent.MainFrame
PL = Main.PlayerList

Pos = 15


function upd()
	getall = PL:GetChildren()
	
	for i=1, #getall do
		getall[i].Position = UDim2.new(0, 0, 0, Pos)
		PL.CanvasSize = UDim2.new(0, 0, 0, Pos)
		Pos = Pos + 120
	end
	Pos = 0
end

game.Workspace.Players.ChildAdded:connect(function(plr)
wait(.1)
	Frm = Instance.new('Frame', script.Parent.MainFrame.PlayerList)
	Frm.Name = plr.Name
	Frm.Size = UDim2.new(0.96, 0, 0, 120)
	Frm.Position = UDim2.new(0, 0, 0, 0)
	Frm.BackgroundTransparency = 1

	IL = Instance.new('ImageLabel', Frm)
	IL.Name = plr.Name
	IL.Image = 'https://www.roblox.com/Thumbs/Avatar.ashx?x=100&y=100&username=' ..plr.Name
	IL.Size = UDim2.new(0, 100, 0, 100)
	IL.Position = UDim2.new(0, 10, 0, 13)
	

	TL = Instance.new('TextLabel', Frm)
	TL.Text = plr.Name
	TL.BackgroundTransparency = 1
	TL.Position = UDim2.new(0.325, 0, 0.1, 0)
	TL.Size = UDim2.new(0, 250, 0, 50)
	TL.Font = 'Cartoon'
	TL.FontSize = 'Size14'
	TL.TextScaled = true
	TL.TextWrapped = true
	TL.TextXAlignment = 'Left' 
	TL.TextColor3 = Color3.new(255, 255, 255)
	upd()
end)





wait(.1)

game.Workspace.Players.ChildRemoved:connect(function(plr2)
wait(.1)
if PL:FindFirstChild(plr2.Name) then
	PL[plr2.Name]:remove()
	upd()
end
	
end)
