Trying to install new smiley set..

[seldom_use]

And am getting this error.

Database Error
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 'LENGTH(code) DESC' at line 2
File: /home/parentin/public_html/Sources/ManageSmileys.php
Line: 990 

Can someone advise what this means and what I should do?

Thanks
