Not again error



The SCT kept giving me the "Did you remember to print "You guess that one already?"

Here's my code which should work:

if guess_row == ship_row and guess_col == ship_col:
    print "congratulations! You sank my battleship!"
    if guess_row not in range(1, 6) or \
       guess_col not in range(1, 6):
        print "Oops, that's not even in the ocean."
    elif board[guess_row-1][guess_col-1] == "X": 
        print "You guess that one already."
        print "You missed my battleship!"
        board[guess_row-1][guess_col-1] = "X"


the string printed should be an exact match, copy paste it from the instructions
