Hi,

I am creating a website, that carries both php and javascript code. However, I am having a problem with my javascript code, where I keep getting an object expected error one line 91. I tries to check to see if it is a php or javascript problem and then concluded that it is most likely related to javascript. Please correct me if im wrong.

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<?php
include("mysqlConnection.php");

$result = @mysql_query('SELECT * FROM courses');
if (!$result) {
 exit('<p>Error performing query: ' . mysql_error() .
     '</p>');
}
$rst1 = @mysql_query('SELECT DISTINCT courseInstructor FROM courses WHERE courseInstructor <> ""');

include("mysqlConnClose.php")
?>

This works fine for me. Did I miss something?
