stuck on sortable('serialize')

stuck on sortable('serialize')


Hi all. I've looked through several threads in this group and various
documentation and blog posts, but I still can't quite figure out why
I'm getting an empty string from sortable('serialize'). Yes, I'm
setting the id="foo_#", although perhaps I'm not fully understanding
the requirement for the id values. If you have some experience with
using sortable, can you please check over my code for obvious rookie
mistakes? I've posted my code here: http://gist.github.com/60065
Thanks in advance to anyone who can help.
Cheers!
