Hi Jason
The error has gone on the results page, however on the details page, deleting still does not work, and I get the following errors:
Warning: mysql_select_db() expects parameter 2 to be resource, null given in D:\xampp\htdocs\websites\demmelsixtus-ag\admin\db_ss_2\startseite_detail.php on line 20
Warning: mysql_query() expects parameter 2 to be resource, null given in D:\xampp\htdocs\websites\demmelsixtus-ag\admin\db_ss_2\startseite_detail.php on line 24
