Why does this textbutton GUI not run it's function when clicked online? [SOLVED]

The script below I have had help to build to make GUI's show for players online as you can see from this link here: https://scriptinghelpers.org/questions/25624/why-does-this-gui-script-not-work-online

However I have now encountered a problem where textboxes will not carry out their functions when clicked on when the game is played online...

function touch(hit)
	if hit.Parent:IsA('Model') then
		local player = game.Players:FindFirstChild(hit.Parent.Name)
		if player then

			local screengui = Instance.new("ScreenGui")
			screengui.Parent = player.PlayerGui

			local textbutton = Instance.new("TextButton")
			textbutton.Parent = screengui
			textbutton.Position = UDim2.new(0.07, 14, 0.73, 15)
			textbutton.Size = UDim2.new(0, 370, 0, 50)
			textbutton.BackgroundColor3 = BrickColor.White().Color
			textbutton.Text = "Click Me!"
			textbutton.BorderSizePixel = 0
			textbutton.FontSize = "Size14"
	 
			-- Bind function to button click
			textbutton.MouseButton1Down:connect(function()
				textbutton.Text = "I've been clicked!"
			end)

		elseif hit.Parent.Parent:IsA('Model') then
			local player = game.Players:FindFirstChild(hit.Parent.Parent.Name)
        	if player then
				local screengui = Instance.new("ScreenGui")
				screengui.Parent = player.PlayerGui

			local textbutton = Instance.new("TextButton")
			textbutton.Parent = screengui
			textbutton.Position = UDim2.new(0.07, 14, 0.73, 15)
			textbutton.Size = UDim2.new(0, 370, 0, 50)
			textbutton.BackgroundColor3 = BrickColor.White().Color
			textbutton.Text = "Click Me!"
			textbutton.BorderSizePixel = 0
			textbutton.FontSize = "Size14"
	 
			-- Bind function to button click
			textbutton.MouseButton1Down:connect(function()
				textbutton.Text = "I've been clicked!"
			end)
		end
	end
end

script.Parent.Touched:connect(touch)

I do not know what the problem with this is, as there is nothing showing in the output, so I have no idea...

EDIT

I managed to solve this by following the advice given in the comments and put it into a localscript, which worked a charm!

Is the script atleast creating the gui? if not is it in a regular script or a local script? Because i do believe that it needs to be a server script so that it can detect every player that touches it then addresses their certain gui.
