Attempt to index nil?

Hi , so there is a problem in a Script that says " Workspace.OmqFroko.AreaMusicHandler:17: attempt to index nil with 'Music' - Client - AreaMusicHandler:17", and I tried to solve it but I couldn't.

-|Script|-

local sound = Instance.new("Sound", script)
sound.Looped = true

location char = script.Parent
location hrp = char:WaitForChild("HumanoidRootPart")

local areasGroup = workspace:WaitForChild("Areas")

location currentArea = nil


game:GetService("RunService").Heartbeat:Connect(function()
raycast location = Ray.new(hrp.Position, hrp.CFrame.UpVector * -1000)
local part = workspace:FindPartOnRayWithWhitelist(raycast, {areasGroup})
if part and part.Parent == areasGroup then
if part ~= currentArea then
sound.SoundId = currentArea.Music.SoundId
sound:Play()
end
else
currentArea = nil
sound:Stop()
end
end)

Also i am not the creator of this script.

First things, workspace:FindPartOnRayWithWhitelist() is deprecated. Why are you spacing your variables? Also, make the variables local? And currentArea is always nil since you've never changed the value of currentArea and that's not a variable.

Can you explain what you're doing? This script is so broken.

are you sure CurrentArea.Music actually exists? that error usually occurs when Studio is trying to find something when that things parent does not exist.
