Fields seem to be mis-wired (for lack of a better term)

[Chris W. Parker]

Hello,
 
I'm having a problem when trying to update a record. I'm trying to set a
field called 'balance' to 0 but instead of 'balance' becoming 0 the
field 'name' becomes 0. None of the other columns are updated
incorrectly.
 
Here's the SQL statement I'm using:

UPDATE `users`
SET `name` = 'First Last'
	AND `email` = 'flast@stripped'
	AND `balance` = 0
	AND `accrual` = 14400
	AND `is_manager` = 1
	AND `is_superadmin` = 1
	AND `type` = 0
	AND `manager_id` = 0
	AND `modified` = NOW()
WHERE `id` = 5

Here's the table definition:
 
CREATE TABLE `users` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `name` varchar(255) NOT NULL default '',
  `email` varchar(255) NOT NULL default '',
  `password` varchar(32) NOT NULL default '',
  `type` tinyint(3) unsigned NOT NULL default '0',
  `manager_id` int(10) unsigned NOT NULL default '0',
  `is_manager` tinyint(1) NOT NULL default '0',
  `is_superadmin` tinyint(1) NOT NULL default '0',
  `fulltime_start` date NOT NULL default '0000-00-00',
  `accrual` smallint(6) NOT NULL default '0',
  `balance` mediumint(9) NOT NULL default '0',
  `created` datetime NOT NULL default '0000-00-00 00:00:00',
  `modified` datetime NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 ;

I did an experiment just now through phpMyAdmin with the following query
and it worked as expected:
 
UPDATE `users`
SET `balance` = 0
WHERE `id` = 5

Only thing I can guess is that there's an obvious error that is not
obvious to me. :)
 
 
 
Thanks,
Chris.
