My SQL statement to delete an entry in MYSQL database fails in PHP

I have a small application i named student admin. I have the following entries in the mysql database, table called 'student':

Students Registry

Foster Johns 1 2002
Edwin Zvav 2 1998
Chenai Mutande 23 2008

Regnumber is my primary key in the database. I pass the regnumber as a parameter from one page to the page that executes a sql statement to delete a student whose regnumber would have been parsed. The page, deleteStudent.php is as follows:

Students Admin:: Student deletion...


include_once "config.php";
include_once "opendb.php";

//verifying the parsed parameter.
echo $myID;
$query = "delete from student where Regnumber = '$myID'";

//echoing the query that will be run
echo $query;


<p> </p>
<p align="center">Student with Registration <i><?php echo $myID ?></i> has been successfully removed from registry! <input type="button" name="backr" value="Home" onclick="window.location.href='http://localhost'" style="height:2em; width:8em;"></P>


When i run the above php page the $myID is echoed correctly and if, for instance i intend to delete student with regnumber '1', the sql statement is echoed as: delete from student where Regnumber = '1'

I am surprised because when i go on to view all the students in registry, EVEN THE DELETED STUDENT IS STILL THERE!!!! If someone willing to assist has additional info he needs, am ready to provide for this seemingly simple problem.....

Change $result=mysql_query(query); to $result=mysql_query($query)or die("Error");
