My face is very very RED !!!

I am SO sorry!

I honestly didn't notice that the search returned the WRONG BOOK!

I really thought this was just a problem in language (that is, non-native English speaker).

I hereby promise to (a) look more carefully in the future and (b) help answer any questions about the code if they occur. (I do have the book, but I admit to not having looked at it in years.)
