How can I get this piano working again or is it beyond the point of repair?

Hey, guys! I'm here due to my script not being able to work. The piano is supposed to play a sound (note) when you press certain keys on your keyboard but as you can see, it is not working. Please help because I have no clue why this isn't working.

Here are my scripts.

Normal script:

01wait(5)
02local KeyTool = script["PianoPlayer V1.1"]:Clone()
03script["PianoPlayer V1.1"]:Remove()
04position = script.Parent.Archive.Position
05local frame = Instance.new("CFrameValue")
06frame.Name = "OriginCFrame"
07frame.Value = script.Parent.Archive.CFrame
08frame.Parent = script.Parent

10local object = Instance.new("ObjectValue")
11object.Value = script.Parent.Parent.Parent

30                script.Parent.Parent.Parent = parent
31            end]]
32            local char = torso.Parent
33            local player = game.Players:GetPlayerFromCharacter(char)
34            if player ~= nil then
35                local hopper = KeyTool:clone()
36                hopper.Parent = player.Backpack
