Why do I get the following error? and How to fix?
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in/home/gaogier/public_html/pages/monsters.php on line 217
If i add the or die part, I get this message.
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘’ at line 1
What do I do?
Here is my code
[php]<?php
