Help with a shop script?

I made this shop script, but it doesn't work. Nothing in the output or script analysis.

items = script.Parent.Frame:GetChildren()

for i = 1, #items do
function buy()
	local item1 = items[i]:FindFirstChild("Item1")
	local item2 = items[i]:FindFirstChild("Item2")
	local item3 = items[i]:FindFirstChild("Item3")
	local item4 = items[i]:FindFirstChild("Item4")
	local item5 = items[i]:FindFirstChild("Item5")
	local Cash = script.Parent.Parent.Parent.Parent.leaderstats:FindFirstChild("Gold")
	if item1 then
		if script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item1.Value).Value > items	[i].item1Price.Value then
			script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item1.Value).Value = 	script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item1.Value).Value - items	[i].item1Price.Value
			local buyitem = game.Lighting:FindFirstChild(items[i].ItemName.Value):Clone()
		end
	end
	if item2 then
		if script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item2.Value).Value > items	[i].item2Price.Value then
			script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item2.Value).Value = 	script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item2.Value).Value - items	[i].item2Price.Value
		end
	end
	if item3 then
		if script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item3.Value).Value > items	[i].item3Price.Value then
			script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item3.Value).Value = 	script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item3.Value).Value - items	[i].item3Price.Value
		end
	end
	if item4 then
		if script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item4.Value).Value > items	[i].item4Price.Value then
			script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item4.Value).Value = 	script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item4.Value).Value - items	[i].item4Price.Value
		end
	end
	if item5 then
		if script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item5.Value).Value > items	[i].item5Price.Value then
			script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item5.Value).Value = 	script.Parent.Parent.Parent.Parent.Materials:FindFirstChild(item5.Value).Value - items	[i].item5Price.Value
		end
	end
	if Cash.Value >= items[i].Cost.Value then
		Cash.Value = Cash.Value - items[i].Cost.Value
		local tool1 = game.ReplicatedStorage:FindFirstChild	(script.Parent.Folder.Value):FindFirstChild(items[i].ItemName.Value):Clone()
		local tool2 = game.ReplicatedStorage:FindFirstChild	(script.Parent.Folder.Value):FindFirstChild(items[i].ItemName.Value):Clone()
		tool1.Parent = script.Parent.Parent.Parent.Parent.Backpack
		tool2.Parent = script.Parent.Parent.Parent.Parent.StarterGear
		print("Purchase successful.")
		
end
items[i].BuyButton.MouseButton1Click:connect(buy)
end
end
