Solve the following python programming problem given the following code:
def main() : 
    show_common_text () 
    autoscale = True 
    if autoscale : 
        show_mode_1_text () 
else : 
        show_mode_2_text () 
director.init (view_width, view_height, autoscale = autoscale) 
    scene = TestScene () 
    world_layer = SquareLand (world_width, world_height) 
    scroller = cocos.layer.ScrollingManager () 
    if autotest : 
        def resize_scroller() : 
            scroller.scale = 0.75 
(w, h) = (world_width, world_height) 
        template_action = ((((((((((((Delay (0.05) + CallFunc (world_layer.teleport_player, 0, 0)) + Delay (1)) + CallFunc (world_layer.teleport_player, (w // 2), 0)) + Delay (1)) + CallFunc (world_layer.teleport_player, (w // 2), h)) + Delay (1)) + CallFunc (world_layer.teleport_player, w, h)) + Delay (1)) + CallFunc (resize_scroller)) + Delay (1)) + CallFunc (director.window.set_size, 800, 600)) + CallFunc (world_layer.update_after_change)) 
        world_layer.do (template_action) 
scroller.add (world_layer) 
    scene.add (template_action) 
    director.run (scene) 

    
    

    Fix the buggy line: scene.add (template_action)

#Here is Python program to fix the buggy line: scene.

scene.add (scroller)
