I need help with my car selection system?

so I'm making a car game and i need a feature so players can spawn cars so I want a menu with all the list of cars and once they click it displays a preview and once they hit spawn it spawns and they get teleported to it here is the current code:

wait()
local Items = game.ReplicatedStorage.Karts
local Platform = game.ReplicatedStorage.Platform
local FirstItem = game.ReplicatedStorage.Karts.Kart
local Camera = workspace.CurrentCamera
local sample = script.Parent.ScrollingFrame.Sample:Clone()
local Item = nil

if not Camera:FindFirstChild("Platform") then
	local Cloned = Platform:Clone()
	Cloned.Parent = Camera
end

if not Camera:FindFirstChild("PrevItem") then
	local Cloned = FirstItem:Clone()
	Cloned.Parent = Camera
	Cloned:MakeJoints()
	Item = FirstItem
	Cloned:SetPrimaryPartCFrame(Camera:FindFirstChild("Platform").TheCFrame.CFrame)
	Cloned.Name = "PrevItem"
end

Camera.CameraType = Enum.CameraType.Scriptable
Camera.CFrame = script.CameraVal.Value

for i,v in pairs(script.Parent.ScrollingFrame:GetChildren()) do
	if v.Name ~= "Sample" then
		v:Destroy()
	end
end

for i,v in pairs(Items:GetChildren()) do
	local a = sample:Clone()
	a.Parent = script.Parent.ScrollingFrame
	a.Position = UDim2.new(0,0,0,25*(i-1))
	a.Name = v.Name
	a.Text = v.Name
	a.Visible = true
end

for i,v in pairs(script.Parent.ScrollingFrame:GetChildren()) do
	v.MouseButton1Click:connect(function()
		if Camera:FindFirstChild("PrevItem") then
			Camera.PrevItem:Destroy()
			local realitem = game.ReplicatedStorage.Karts:FindFirstChild(v.Name)
			if realitem then
				local Cloned = realitem:Clone()
				Cloned.Parent = Camera
				Cloned:MakeJoints()
				Cloned:SetPrimaryPartCFrame(Camera:FindFirstChild("Platform").TheCFrame.CFrame)
				Cloned.Name = "PrevItem"
				Item = realitem			
			end
		end
	end)
end

script.Parent.Play.MouseButton1Click:connect(function()
	if Item ~= nil then
		local Cloned = Item:Clone()
		Cloned.Parent = Camera
		Cloned:MakeJoints()
		Cloned:SetPrimaryPartCFrame(workspace.sPawn.CFrame)
		Cloned.Name = "PrevItem"
		game.Players.LocalPlayer.Character.HumanoidRootPart.CFrame = Cloned.PrimaryPart.CFrame
		Camera.CameraSubject = game.Players.LocalPlayer.Character.Humanoid
		Camera.CameraType = Enum.CameraType.Custom
	end
end)

but once I add a new car it doesn't spawn on the platform and breaks the code
