How do I use pathfinding?

I am trying to add pathfinding to my game but it does not work.

I have it set so that at the start of the layout it adds Sprite3 as obstacle (my blockade) and find path to Sprite.X, Sprite.Y (my player)

and so that every tick it will move along path.

I was able to get it to move by setting the speed to 200, but he doesn't go to the player
