Hello everyone, I'm coming to you because I have a mistake that I can't find or correct, could you help me? My error:

SnowArea is not a valid member of Folder

My code:

local SoundRegionsWorkspace = game.Workspace:WaitForChild("SoundRegions")
local Found = false
while wait(1) do
 for i, v in pairs(SoundRegionsWorkspace:GetChildren())do
  Found = false
  local region = Region3.new(v.Position - (v.Size/2),v.Position + (v.Size/2))
  local parts = game.Workspace:FindPartsInRegion3WithWhiteList(region, game.Players.LocalPlayer.Character:GetDescendants())  
  for _, part in pairs(parts) do
   -- Loop one by one through the parts table
   if part:FindFirstAncestor(game.Players.LocalPlayer.Name) then
    print("Player was found")
    Found = true
    break
   else
    Found = false
	print("Player was not found in region")
   end
  end
  if Found == true then
   -- Start playing some music
   if script.Parent.SoundRegions[v.Name].IsPlaying == false then
	    script.Parent.SoundRegions[v.Name]:Play()
	    break
   end
  else
   script.Parent.SoundRegions[v.Name]:Stop()
  end
 end
end

In Workspace, I have a folder named SoundRegions with my part SnowArea and in StarterGui, I have a folder named too: SoundRegions with my sound and my localscript is too, in StarterGui

Thank you in advance.
