CREATE TABLE `renters` (
  `id` int(11) NOT NULL auto_increment,
  `first_name` varchar(100) default NULL,
  `last_name` varchar(100) default NULL,
  `email1` varchar(100) default NULL,
  `email2` varchar(100) default NULL,
  `email3` varchar(100) default NULL,
  `phone1` varchar(20) default NULL,
  `phone2` varchar(20) default NULL,
  `phone3` varchar(20) default NULL,
  `information` varchar(4000) default NULL,
  `description` varchar(9000) default NULL,
  PRIMARY KEY  (`id`),
  UNIQUE KEY `email1` (`email1`)
) ENGINE=MyISAM AUTO_INCREMENT=32 DEFAULT CHARSET=utf8$$








INSERT INTO renters (first_name,last_name,email1,email2,email3,phone1,phone2,phone3,information,description) VALUES ('test','','derrickjmiller1@gmail.com','','','','','','','') ON DUPLICATE KEY UPDATE renters set description=concat(description,'somthing to add to description')

Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'set description=concat(description,'somthing to add to description')' at line 1

There's no need to modify the table.  You just need to correct your insert statement.  Please take time to look at the manuals and check the correct syntax for the command you are using.  See http://dev.mysql.com/doc/refman/5.5/en/insert-on-duplicate.html

After ON DUPLICATE KEY UPDATE there's no need to repeat the table name nor use the keyword "set".  It should just be:

INSERT INTO renters (first_name,last_name,email1,email2,email3,phone1,phone2,phone3,information,description) VALUES ('test','','derrickjmiller1@gmail.com','','','','','','','') 
ON DUPLICATE KEY UPDATE description=concat(description,'somthing to add to description');
