Well after my faux pas with mysql_insert_id() I can at the least 
*try* to make up for it! The LIMIT 1 would return only the latest 
entry, ie: the column with the largest timestamp. So just add 
whatever else to the SELECT statement that you need to retrieve 
(user_id, column_this, column_that, column_blue, column_red, etc...).
