Puppet users - Oct 2012 - Passing parameters to Class from Dashboard

Good day to all:

I''m trying to use the browser''s dashboard to pass a parameter
variable to a
simple class.

class hello ( $file_name ) {
  file {"/tmp/${file_name}":
    owner => ''ubuntu'',
    group => ''ubuntu''
  }
}

But when I run the agent update I keep getting

ubuntu@db:~$ sudo puppet agent --test
info: Retrieving plugin
info: Loading facts in /var/opt/lib/pe-puppet/lib/facter/facter_dot_d.rb
info: Loading facts in /var/opt/lib/pe-puppet/lib/facter/puppet_vardir.rb
info: Loading facts in /var/opt/lib/pe-puppet/lib/facter/root_home.rb
err: Could not retrieve catalog from remote server: Error 400 on SERVER: 
Must pass file_name to Class[Hello] at 
/etc/puppetlabs/puppet/modules/hello/manifests/init.pp:1 on node 
db.company.com

Any ideas on what I''m doing wrong?

Thanks in advance.

I just found the answer in another thread.

In case somebody is looking to pass parameters from the dashboard to your 
classes you should
reference those variables like this:

$::foo instead of $foo which are local variables

Hope it helps
