  1. There are a bunch of errors I'm getting which seem to be related to the use of mysqli. I'm thinking its related to my use of mysql_connect instead of mysqli_connect, but the reason I'm not sure is 1. lack experience 2. the mysqli_connect.php looks. Useful background info as follows: (error message, code from add_prints.php, currently running ver php 5.2.5 and mysql 5.0.45.
