i’m sorry, i’m just in a rush to our project. please understand.
my main problem is that when the game.lua is finished, the scene reload back at create_game.lua, and within the create_game.lua, it will go to set.up.lua page. the values in that set_up.lua  is retained, i dont know where to put the clean() function of director so that when it goes back to set_up.lua you can set up new pieces
we’re also using parsing, it works well. 
game.lua endgame function() when the game is finished.

and here is the set_up.lua module. the values here is RETAINED from the previous game.

i’m hoping that the scene will reload in the set_up.lua page but the values from the previous game is retained and the player can’t set up a new page because of it.
