Why can my weapon shop only buy 1 item?

I made a weapon shop, however whenever i try to buy a different item it always just buys the first one again.

heres my code

local camera = game.Workspace.Camera
local cam = game.StarterGui.Shop1.Cam
local cam1 = game.Workspace.Shop1.ShopCam1
local cam2 = game.Workspace.Shop1.ShopCam2
local cam3 = game.Workspace.Shop1.ShopCam3
local cam4 = game.Workspace.Shop1.ShopCam4
local cam5 = game.Workspace.Shop1.ShopCam5
local cam6 = game.Workspace.Shop1.ShopCam6


function leftClick()
	if game.StarterGui.Shop1.Cam.Value == 1 then
		if script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value >= 10 then
			script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value = script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value - 10
			game.Lighting.KnifeTools["Wooden Knife"]:Clone().Parent = script.Parent.Parent.Parent.Parent.Backpack
			script.Parent.Parent.TextButtonBuy.Text = "Buy - $10"
			script.Parent.Parent.TextBox.Text = "Wooden Knife"
			end
	else if game.StarterGui.Shop1.Cam.Value == 2 then
			if script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value >= 150 then
				script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value = script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value - 150
				game.Lighting.KnifeTools["Stone Knife"]:Clone().Parent = script.Parent.Parent.Parent.Parent.Backpack
				script.Parent.Parent.TextButtonBuy.Text = "Buy - $150"
					script.Parent.Parent.TextBox.Text = "Stone Knife"
					end
		else if game.StarterGui.Shop1.Cam.Value == 3 then
				if script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value >= 500 then
					script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value = script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value - 500
					game.Lighting.KnifeTools["Metal Knife"]:Clone().Parent = script.Parent.Parent.Parent.Parent.Backpack
					script.Parent.Parent.TextButtonBuy.Text = "Buy - $500"
							script.Parent.Parent.TextBox.Text = "Metal Knife"
							end
				else if game.StarterGui.Shop1.Cam.Value == 4 then
						if script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value >= 2500 then
						script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value = script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value - 2500
						game.Lighting.KnifeTools["Stainless Steel Knife"]:Clone().Parent = script.Parent.Parent.Parent.Parent.Backpack
						script.Parent.Parent.TextButtonBuy.Text = "Buy - $2,500"
									script.Parent.Parent.TextBox.Text = "Stainless Steel Knife"
									end
					else if  game.StarterGui.Shop1.Cam.Value == 5 then
						if script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value >= 10000 then
							script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value = script.Parent.Parent.Parent.Parent.leaderstats.Cash.Value - 10000
							game.Lighting.KnifeTools["Golden Plated Knife"]:Clone().Parent = script.Parent.Parent.Parent.Parent.Backpack
											script.Parent.Parent.TextButtonBuy.Text = "Buy - $10,000"
						end
					end						script.Parent.Parent.TextBox.Text = "Golden Plated Knife"
				end
			end
		end
	end
end

script.Parent.MouseButton1Click:Connect(leftClick)

im confused why this doesnt work because no matter which one I try and buy it always gives me the wooden knife. The cams are there because im moving the camera to a different spot in the workspace to look at the weapons.
