count

If my table looks like this:

daily_individual_tracking', 'CREATE TABLE `daily_individual_tracking` (
  `daily_individual_tracking_id` int(10) unsigned NOT NULL auto_increment,
  `daily_individual_tracking_date` date NOT NULL default ''0000-00-00'',
  `sales` enum(''no'',''yes'') NOT NULL COMMENT ''no'',
  `repairs` enum(''no'',''yes'') NOT NULL COMMENT ''no'',
  `shipping` enum(''no'',''yes'') NOT NULL COMMENT ''no'',
  PRIMARY KEY  (`daily_individual_tracking_id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=latin1

basically the fields can be either yes or no.

How can I count how many yes's their are for each column over a date range?

Thanks!!
