Why does my model not get destroyed?

I am not sure if the remote event called "Delete" is getting called. I am using zblox's grid-placement tutorial.

Here is the Client side of the script:

--Services
local runService = game:GetService("RunService")

--Instances
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

local DeleteRE = game.ReplicatedStorage.Events.Delete

local obj

--Bools
local deleteToggle = false

--Functions/Events
script.Parent.MouseButton1Click:Connect(function()
	if deleteToggle then
		deleteToggle = false
	else
		deleteToggle = true
	end
end)

mouse.Button1Down:Connect(function()
	if obj then
		DeleteRE:FireServer(obj.Parent)
	end	
end)

runService.RenderStepped:Connect(function()
	if deleteToggle then
		if mouse.Target then
			if mouse.Target == "Primary" then
				obj = mouse.target
				print(obj)
			end
		end
	end
end)

And here is the server-side:

local DeleteRE = game.ReplicatedStorage.Events.Delete

DeleteRE.OnServerEvent:Connect(function(plr, obj)
	if obj.Primary then
		local stats = plr.leaderstats
		local cash = stats.Cash
		
		cash = cash.Value + obj.Price.Value/2
		
		obj:Destroy()
	end
end)

Thanks for the help!
