Peter I'm sorry, I sort of abandoned this post since I found I had other problems with the scripts and posted another question above. I have at this point the checkboxes appearing, the mysql_num_row is not working yet, but that can got kicked down the road a bit. Thank you for all your help, I'm trying to formulate me next question for the aforementioned 2nd post.
