When I'm debugging forms to understand the structures I use something like

drupal_set_message('<pre>' . print_r($form_values, TRUE) . '</pre>')

so I can see the contents of the arguments in the callback functions.  
The first argument of form_set_error should match the form element name 
being flagged with an error and is used in the form validate function.

You might be able to rewrite the form_set_error as ``form_set_error('', 
'error message')'' depending on what you need.  Also, take the deadwood 
comments with a grain of salt because the comment could be a false 
positive based on regular expressions.  Deadwood only gives a starting 
point, it doesn't do the whole job.
