  When a you have a matrix of buttons [or menuCells for that matter], the
  sender is the matrix itself, not the individual button. To get its tag, 
  you could :
	  myTag = [[sender selectedCell] tag];

Or you could look at its position, and base your logic on #defines,
remembering that 0 is the first position, then:

    int row = [sender selectedRow];   // columnar list
    switch (row) {
      ....

One day I woke up and it all made perfect sense.
