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
					
					--show description
					local newgui = workspace.MainGameScript.ItemGet:clone()
					newgui.Parent = player.PlayerGui
					newgui.Frame.Description.Text = description
					--thread separately so it doesn't hold up the rest of the script
					Spawn(function()
						newgui.Frame:TweenPosition(UDim2.new(0.5, -150, 0.5, -60), "Out", "Elastic", 2)
						wait(6)
						newgui.Frame:TweenPosition(UDim2.new(0.5, -150, 0, -300), "Out", "Elastic", 2)
						wait(1)
						if player:findFirstChild("Checkpoint") then
							--reset checkpoint
							player.Checkpoint.Value = Vector3.new()
						end
						if respawn then
							if player:findFirstChild("Checkpoint") then
								--reset checkpoint
								player.Checkpoint.Value = Vector3.new()
							end
							player:LoadCharacter()
						else
							newgui:Destroy()
						end
					end)
					
				else
					
					--let the player know they already have this item
					local newgui = workspace.MainGameScript.ItemGet:clone()
					newgui.Parent = player.PlayerGui
					newgui.Frame.Description.Text = "You already have this item!"
					--thread separately so it doesn't hold up the rest of the script
					Spawn(function()
						newgui.Frame:TweenPosition(UDim2.new(0.5, -150, 0.5, -60), "Out", "Elastic", 2)
						wait(6)
						newgui.Frame:TweenPosition(UDim2.new(0.5, -150, 0, -300), "Out", "Elastic", 2)
						wait(1)
						if respawn then
							if player:findFirstChild("Checkpoint") then
								--reset checkpoint
								player.Checkpoint.Value = Vector3.new()
							end
							player:LoadCharacter()
						else
							newgui:Destroy()
						end
					end)
					
				end
			end
		end
		
		debounce = false
	end
	
end)
