I've been trying to get this Sudoku game working, and I am still failing some of the individual functions. All together the game works, but when I run it through an "autograder", some test cases fail.. Currently I am stuck on the following function, placeValue, failing. I do have the output that I get vs. what the correct one should be, but am confused..what is something going on?

EDIT: I do not know what input/calls they make to the function.

What happens is that "invalid row" is outputted after every placeValue call, and I can't trace why..

Here is the output (mine + correct one) if it's at all helpful: http://pastebin.com/Wd3P3nDA

Here is placeValue, and following is getCoords that placeValue calls..

void placeValue(Square board[BOARD_SIZE][BOARD_SIZE])
{   
    int x,y,value;  

    if(getCoords(x,y))
    { 

        cin>>value;

        if(board[x][y].permanent)
        {
            cout<< endl << "That location cannot be changed";   

        }
        else if(!(value>=1 && value<=9))
        {
            cout << "Invalid number"<< endl;
            clearInput();
        }
        else if(validMove(board, x, y, value))  
        {
            board[x][y].number=value;
        }
    }
}


bool getCoords(int & x, int & y)
{
    char row;
    y=0;

    cin>>row>>y;
    x = static_cast<int>(toupper(row));
   if (isalpha(row) && (x >= 'A' && x <= 'I') && y >= 1 && y <= 9)
   {
      x = x - 'A'; // converts x from a letter to corresponding index in matrix
      y = y - 1;   // converts y to corresponding index in matrix
      return (true);
   }
   else if (!(x >= 'A' && x <= 'I'))
   {
    cout<<"Invalid row"<<endl;  

    clearInput();
    return false;
   }
   else 
   {
    cout<<"Invalid column"<<endl;
    clearInput();
    return false;
   }

}
