Nice puzzle, spoiled very slightly by the fact that the answer to the question doesnt quite work due to the extra letter. Took me a while to figure out what to put in the barred off cell, being only a very occasional dabbler in the game, but all makes perfect sense when you see it.
Maybe I'm missing something but i don't see the potential ambiguity that others have referred to here and elsewhere. Seems like there's only one way of following the instructions to me.
