Clicking a TextButton in a BillboardGui won't work?

I'm trying to make it so that if you click the TextButton then it will print "Clicked", but it doesn't work. Here is the code:

function ToggleGui(Part)
	local a = Instance.new("BillboardGui",Part)
	a.Size = UDim2.new(1,0,1,0)
	a.StudsOffset = Vector3.new(0,0,0)
	a.AlwaysOnTop = true
	a.Active = true
	a.Adornee = Part
	a.Name = "Gui"
	
	local s = Instance.new("TextButton",a)
	s.BackgroundColor3 = BrickColor.new("Light stone grey").Color
	s.BackgroundTransparency = .7
	s.BorderSizePixel = 0
	s.Size = UDim2.new(1,0,1,0)
	s.Position = UDim2.new(0,0,0,0)
	s.Active = true
	s.Font = "Legacy"
	s.Text = "Use"
	s.TextColor3 = BrickColor.new("Institutional white").Color
	s.TextStrokeTransparency = 0
	s.TextWrapped = true
	s.TextScaled = true
	
	s.MouseButton1Down:connect(function()
		print("Clicked")
	end)
end

Everything shows up, but the TextButton just wont work. There are no errors in the Output. I've tried using MouseEnter, MouseButton2Down, moving the StudsOffset, moving the GUI into PlayerGui, and changing Sizes and Positions, though it still doesn't work. Is it just that there's something wrong with the Part that I place it in or is there something wrong with the code?

"Everything shows up, but the TextButton just wont work." I don't understand what you mean, but this is your problem:

s.MouseButton1Down:Connect(function()

The line that it's at is only correct if you want it to print "Clicked". Otherwise it will do nothing else than that. Here's the solution:

function ToggleGui(Part)
    a = Instance.new("BillboardGui",Workspace.Part)
    a.Size = UDim2.new(1,0,1,0)
    a.StudsOffset = Vector3.new(0,0,0)
    a.AlwaysOnTop = true
    a.Active = true
    a.Adornee = Part
    a.Name = "Gui"

    s = Instance.new("TextButton",a)
    s.BackgroundColor3 = BrickColor.new("Light stone grey").Color
    s.BackgroundTransparency = .7
    s.BorderSizePixel = 0
    s.Size = UDim2.new(1,0,1,0)
    s.Position = UDim2.new(0,0,0,0)
    s.Active = true
    s.Font = "Legacy"
    s.Text = "Use"
    s.TextColor3 = BrickColor.new("Institutional white").Color
    s.TextStrokeTransparency = 0
    s.TextWrapped = true
    s.TextScaled = true

        print("Clicked")
    end)
end
s.MouseButton1Down:connect(ToggleGui)
