How to make a drag box?

Questions
#1

in trying to make it so that whn the player clicks and drags on screen there is a box that follows the mouse, similar to draging in the windows main menu. but the box is not showing up on screen. can anyone help me? this is the script for the boxx object

function init(self)
	msg.post(".", "acquire_input_focus")

end

  -- Initial click position
local is_dragging = false -- Flag to track if dragging is in progress
local last_action

function on_input(self, action_id, action)
	if action_id == hash("drag") then
		if action.pressed then
			initial_click_position_x = action.x
			initial_click_position_y = action.y
			
			-- Mouse button pressed
			is_dragging = true
			last_action = action
			print("Mouse button pressed")
			go.set("#box", "tint", vmath.vector4(1, 1, 1, 1)) -- Set color to indicate visibility
		elseif action.released then
			-- Mouse button released
			is_dragging = false
			print("Mouse button released")
			go.set("#box", "tint", vmath.vector4(1, 1, 1, 0)) -- Set color to indicate invisibility
		end
	end
end

function update(self, dt)
	if is_dragging and last_action then
		local current_position = vmath.vector3(last_action.x, last_action.y, 1)
		local size = vmath.vector3(math.abs(current_position.x - initial_click_position_x), math.abs(current_position.y - initial_click_position_y), 1)
		local position = vmath.vector3((current_position.x + initial_click_position_x) / 2, (current_position.y + initial_click_position_y) / 2, 1)

		-- Set the position and size of the box
		size.x = math.max(size.x, 0.001)
		size.y = math.max(size.y, 0.001)
		
		-- Set the position of the box
		go.set_position(position)
		go.set_scale(size)
		print("Box position set")
	end
end
