Python not correctly choosing numbers for my game.

[LavaCreeperKing]

Yes I am trying to make Sudoku. I am using PyQt. I took your code and put it in place of my code but I am still having the same problems. I have a 9 by 9 grid with blocks of 3 by 3. Most of the numbers get chosen just fine but there are some that are not and for some reason when I put your code in I now get problems of some of the buttons not even getting a number.
