books["Gravity's Rainbow"] = :splendid doesn't work #149

gives out error "NameError: undefined local variable or method `book' for main:Object "

Did you define books first? I tried books = {} then books["Gravity's Rainbow"] = :splendid and it worked correctly.

Note your error message uses the work book instead of books. Maybe you mistyped it?

It failed for me also. In addition, I find the tutorial painstaking because I cannot delete a character if I make a single typo. I also can't go back and look at the instructions for the previous screen. It appears that if you make a mistake along the way, the rest of the tutorial can break.

nanothief, you are absolutely right. I did a typo. "Books", not "book".

deonomo, you can delete a char by putting cursor on and then pressing backspace or delete. Jjust pressing backspace doesn't work, I know.
