Correct. I was careful to insert the set() function into self so that it
would work. I actually tried it before I posted it, so I know it worked
as written in my message. But you definitely need three arguments (my
first one was the hidden self argument of the ':' syntactic sugar), and
you definitely need to put the name of the field in quotes.
You (Leigh) might want to consider Etan's advice, too.
