Hi,
You can't use default_values() to populate a Select element.
You need to use options() or values().
You can then call default_values() to state which select item will be
selected by default when the form is first displayed.

See these docs:

http://search.cpan.org/~perler/HTML-FormFu-0.09005/lib/HTML/FormFu/Role/Element/Group.pm#values
http://search.cpan.org/~perler/HTML-FormFu-0.09005/lib/HTML/FormFu.pm#default_values

Hope this helps,
Carl
