That should be IS_INT_IN_RANGE(1965,2017, "Not a valid year of issue")

My apologies. This field does not get a dropdown.
*If *I do
year_set = set()
for x in range(1965,2017):
year_set.add(x)
db.define_table('mytable,
Field('IssueYr', 'integer', requires=IS_IN_SET(year_set,
zero=None,
error_message="Not a valid year of issue")),
[....])
I do get a drop-down, but it's pretty ugly to be recreating the set on
every call.
(Ugh, I just realized that I'm doing exactly that with some other fields.
One of those sets has 50 strings in it.).
(The other observation, from working with credit card forms, is that a
drop-down with 10-20 entries that all begin with the same substring isn't
much fun to use.)
