Your title should be specific! Describe your problem concisely.?

It was just saying Your title should be specific! Describe your problem concisely. And i didn't know what to make the title. Any way, here is the question: can you help me with this code? There are no errors in the code but it output "Bad Id"

function onTouched(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player then
        local gametp = math.random(4500000000,3999000000)
        if gametp >= 0 then
        local name = (game:GetService("MarketplaceService"):GetProductInfo(gametp).Name)
        print(name)
        print(gametp)
        if string.match(name, "'s Place") then 
        warn("Bad Place")
        local gametp = math.random(4500000000,3999000000)
        else
        game:GetService("TeleportService"):Teleport(gametp, player)
        end
        else
        warn("Bad Id")
        end
    end
end
script.Parent.Touched:connect(onTouched)

I dont know what causes it. I tried changing

 local gametp = math.random(4500000000,3999000000)

To

 local gametp = math.random(3999000000,4500000000)

But it then also dont works. Got any help?

Sorry for my bad english.
