Cann't figure out what is wrong... my code works but cannt progress as i get this error:

Oops, try again. Make sure you print "Oops, that's not even in the ocean." if the user guesses a row or column that is off the board.

<What do you expect to happen instead?>

<do not remove the three backticks below>
```python

Replace this line with your code.

## wow

thanks! I cann't believe that it was just the miss spelling of Oops... or should I say Opps!

I DID THE SAME THING! Silly o willy

I think the instructions were very much ambiguous and thats why you got confused but if you follow the standard Boolean expression structure, you shouldn't be far off to the next lesson
