Hi Douglas,

I’m not sure why that would be the case as it has worked for me. Perhaps a clue 
it that my code only handles the 4 common cases. Could your picture be one of 
the other four cases? Not sure. I can give you the site I found that helped me 
understand this (to the small degree that I understand it!):

Good luck.
