attachment_fu problem

Rails noob here,
I am having trouble getting a simple attachment_fu file upload form to
work. I am using Mike Clark's tutorial on attachment_fu - . My code is the same as
the tutorial but with a few minor naming conditions that are different
and the form. I have RMagick installed and it's dependencies as well
as the attachment_fu plugin. It's not saving in the controller and I
am getting the message "there was a problem". I am not getting any
Rails or Ruby errors. Can anyone is my code:

new.rhtml :

When an active record model doesn't save it means: either a
before_save callback returned false, or there were validation errors.
You're not showing any validation errors in the new.rhtml view:

<%= error_messages_for :whatever %>

If anyone can suggest fixes, send them in as patches please. I don't
have a windows machine handy at the moment.
