Is There A Bug In My Shop Gui?

My store gui does not work when I click to buy the item. Here is the script:

player = script.Parent.Parent.Parent.Parent.Parent
kills = player.leaderstats.Knockouts
Item = game.ReplicatedStorage.SpeedCoil

function buy()
if kills.Value >= 8 then

	kills.Value = kills.Value - 0

        Item:clone().Parent = player.Backpack

	wait(2)
else
        script.Parent.Text = "Not Enough Funds" 
	wait(3)
        script.Parent.Text = "Speed Coil"
end
end

script.Parent.MouseButton1Down:connect(buy)

Possible diagnostics:

• not in a LocalScript
• Active property of the Gui object is false
• Gui object is not a button

I tried to make a different one an had no luck, no errors or even outputs were given. Whats wrong here?

Cash = script.Parent.Parent.Parent.Parent.Parent.leaderstats.KOs

function onClick()
	if Cash.Value >= 8 then
		Cash.Value = Cash.Value - 0
			local item = game.ServerStorage.SpeedCoil:clone()
			item.Parent = script.Parent.Parent.Parent.Parent.Parent.StarterGear
			item.Parent = script.Parent.Parent.Parent.Parent.Parent.Backpack
			print("Yay")
	else
		script.Parent.Text = 'Nope'
		wait(3)
		script.Parent.Text = 'Speed Coil'
		print("Yay?")
	end
end

script.Parent.MouseButton1Click:connect(onClick)
