PLEASE SQL SYTAX ERROR PROBLEM

Am designing a simple php forum platform with mysql database.

But on redirecting from a page called main_forum.php to a page called view_topic.php, am stuck with this error 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 'WHERE id='4'' at line 1
