Also, James, each table row has a unique id. it will be called something like id="group34" or id="group35" - no two are the same. It's info that is related to the ID of the database.
So when my jQuery posts to addgroup.php, it inserts the data into the database, and then I use the mysql_inser_id() function to retrieve the ID of the entry I just made. I then return that data to the main page, and I simply want to stick it below all of the data that was generated by PHP. To give you an idea - here is a screen capture of it in action, and some of the issues along with it: http://www.nathanledet.com/removingdata_jquery.mov
