Very strange error when trying to locate a part by name

Heyy, I’m trying to make a function to create a tween. The player creates two parts and names them as he wants then the player writes which part will be with the touched function and the other part will play the tween when the player touched the first part. In the video I showed what happens and what is the error:

I will be grateful for your help. Here is the script:

IdTouch.FocusLost:Connect(function()
	for _, v in pairs(workspace:WaitForChild("Parts"):WaitForChild(game.Players.LocalPlayer.Name.."_s folder"):GetChildren()) do
		if v:IsA("Part") then
			if IdTouch.Text == v.Name and TweenId.Text ~= v.Name then
				table.insert(TouchTable, v)
			else
				TouchTable = {}
			end
		end
	end
end)

TweenId.FocusLost:Connect(function()
	for _, v in pairs(workspace:WaitForChild("Parts"):WaitForChild(game.Players.LocalPlayer.Name.."_s folder"):GetChildren()) do
		if v:IsA("Part") then
			if TweenId.Text == v.Name and IdTouch.Text ~= v.Name then
				table.insert(TweenTable, v)
			else
				TweenTable = {}
			end
		end
	end
end)
