Reward Collectable Script? (Oozlebachr's Adventure Kit)

So, the script is for the dialog and the collectable. So, I have it so the item you give to the person is destroyed and gives you a collectable. I'm not a good scripter so I may make some obvious mistakes, but I just need a few pointers.~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~ game.Players.LocalPlayer.Backpack.Baby:Destroy()

local identifier = "gemtesterbester" local stat = "Gems" local description = "You found iDarricks Baby. Now he ate baby. You monster." local respawn = false local debounce = false

if not debounce then
    debounce = true

    local player = game.Players:GetPlayerFromCharacter(part.Parent)
    if player then
        if player:findFirstChild("OneTimeItems") and player:findFirstChild("leaderstats") and not player.PlayerGui:findFirstChild("ItemGet") then
            if not player.OneTimeItems:findFirstChild(identifier) then

                --create an identifier (accoutrements have cool icons)
                local newidentifier = Instance.new("Accoutrement",player.OneTimeItems)
                newidentifier.Name = identifier

                --update stats
                local stats = player.leaderstats:findFirstChild(stat)
                if stats then
                    stats.Value = stats.Value + 1
                else
                    print(stat.." not found in leaderstats")
                end

                newgui.Frame.Description.Text = description
                --thread separately so it doesn't hold up the rest of the script
                Spawn(function()

                    if respawn then
