So i am trying to work through PBL's tutorial on Sudoku and there are parts that are a bit over my head. I have my grid built so far, and the part that i am trying to get right now, is adding individual elements to each button. I know i want to use a switch statement with the different drawing parts, but i can only get one image to post. I will eventually get into selecting a cell, but i want to get this part working first. I would love some help getting these graphics to post to different cells.

I have worked more on this..and have edited the above code to be this...but i am still not getting the buttons to display..i am now getting the images to work, but not the buttons.

    setVisible(true);
  
    SudokuBase board = sb;
    Rows = board.rows;
    Cols = board.columns;

hooray!! i figured out that part...now to add them as different keys in the sudoku board and to set my sudoku size to whatever i want to set this as.
