Last

http://prntscr.com/a8geq1

local Item = tostring(script.Parent.Parent.Item.Value)

Player = game.Players.LocalPlayer

leaderstats = Player.Backpack:WaitForChild(Item.Value)





Dur = leaderstats.CurrentDurability

while true do
	wait(.1)
	
	script.Parent.Text = Item
	
	
	
	
end

The first script requires you to be editing a value so at the end of Durability put .Value e.g.

Dur = script.Parent.CurrentDurability.Value

The second script is basically saying the GUI doesn't exist in PlayerGUI, has you misspelt the name of it? If not, make sure it's in StarterGUI.

Use WaitForChild

I cannot stress to you enough the importance of actually waiting for an Instance member before tying to access it, particularly regarding the PlayerGui.

Gui = Player.PlayerGui:WaitForChild("Durrability"):WaitForChild("Durrability"):WaitForChild("Background"):WaitForChild("DurVal");
Gui2 = Player.PlayerGui.Durrability.Durrability.Background:WaitForChild("DurVal2");
Gui3 = Player.PlayerGui.Durrability.Durrability.Background
