Thanks for the comments. The last names come from a large pool of last
names. Only a much smaller number of last names are available for the
user to select. So really I am just using web2py's "requires" to force
the form to show the available list. Technically, I would then have to
validate the selection against the much larger pool of last names. But
I don't know what names are in that pool! I don't really have to
validate the selection. Just the fact that it was available on the
menu means it was valid for this.

I know this must sound confusing! In case you must know, this all has
to do with letting internal users get accounts on Second Life. We need
to create a Web form front end for users to register and so we can
keep track of who is doing that.
