Why is my sound ID input system not working? FIXED

So im trying to make a system where a player can put a sound ID for some cash and play that sound

local button = script.Parent
local soundBox = button.Parent.SoundBox
local event = game.ReplicatedStorage.AdviceSound
local db = game.ReplicatedStorage.DiscoDebounce
local plr = game.Players.LocalPlayer
local marketplaceService = game:GetService("MarketplaceService")

button.MouseButton1Click:Connect(function()
	if db.Value == false then
		if plr.leaderstats.Cash.Value >= 300 then
			local input = soundBox.Text
			local convertion = tonumber(input)
			if convertion ~= nil then
				local asset
				local success, result = pcall(function()
					asset = marketplaceService:GetProductInfo(convertion, Enum.InfoType.Asset)
				end)
				
				if success and asset.AssetType == 3 then
					event:FireServer(convertion)
					print(success)
				elseif not success then
					button.Text = "Invalid ID"
					button.BackgroundColor3 = Color3.new(255, 0, 0)
					wait(2)
					button.Text = "Apply ($300)"
					button.BackgroundColor3 = Color3.new(0, 255, 0)
					print(result)
				end
			end
		end
	end
end)

db.Changed:Connect(function()
	if db.Value == true then
		button.Text = "Cooldown"
		button.BackgroundColor3 = Color3.new(255, 0, 0)
	else
		button.Text = "Apply ($300)"
		button.BackgroundColor3 = Color3.new(0, 255, 0)
	end
end)

event.OnClientEvent:Connect(function(name, duration)
	local fixedDuration = math.ceil(duration)
	button.Parent.SoundName.Text = "Name: "..name
	for i = fixedDuration, 0, -1 do
		button.Parent.Time.Text = "Time: "..tostring(i)
		wait(1)
	end
	game.ReplicatedStorage.SoundFinished:FireServer()
	button.Parent.SoundName.Text = "Name:"
	button.Parent.Time.Text = "Time:"
end)

and there is a pcall function that checks if the ID put by the user is a valid audio ID but even though I put a valid audio ID the if statement under the pcall doesn't detect it as an AssetType 3 (audio type)?

I fixed it

The problem was that it was AssetTypeId not AssetType
