MouseButton1Click is not a valid member of TextBox?

script.Parent.Parent.TextBox.MouseButton1Click:Connect(function()
 
	local textbuttoninput = script.Parent.Parent.TextBox.Text
	local sound = script.Parent.Parent.Parent.Sound
	sound.SoundId = 'rbxassetid://'..textbuttoninput
	sound:Play()
end)

It keeps saying that MouseButton1Click is not a valid member of TextBox in the output, It had worked before until I tweened the frame it was in.
