Warning: mysql_free_result

When previewing a directory detail page, at the bottom I have the following:

Warning: mysql_free_result(): 6 is not a valid MySQL result resource in /data/25/2/98/45/2424045/user/2657060/htdocs/test/directory_detail.php on line 214

Lines 209-215 of the page say:

<?php
mysql_free_result($rs_directory_detail);

mysql_free_result($rs_session_detail);

mysql_free_result($rs_directory_detail);
?>

I haven't added those so I assume they were added when different behaviors were added. Not sure why line 214 is the problem but what do I do about it?

Thank you.

delete line 214:
mysql_free_result($rs_directory_detail);


it is a duplicate of line 210.

Thanks, Jason. I thought about trying that but wasn't sure if it was needed. Sort of like finding </div></div> at the end of a page.

Thank you.

you're welcome.
