[nfbcs] Can anyone help me understand what I'm doing wrong here?

Thanks. I figured it out. I forgot to return inventory. I also made 
another adjustment since it was returning two of certain items when 
there was only supposed to be one. Moving the setdefault() method under 
the if statement instead of above it fixed that. I think it looks good now.
