In localhost, my php pages work perfectly, all 3 jqGrids are populated. When I put my php files on my website, the jqGrids remain empty. Using Firebug on Firefox, I have narrowed down the problem to here:

$isic = $_GET['isic']; //This is the value being passed to this php page, it works

$result = mysql_query('SELECT COUNT(*) AS count FROM command WHERE ISIC = ' . $isic); // $result remains empty

$row = mysql_fetch_array($result,MYSQL_ASSOC);  // $row remains empty

$count = $row['count']; //$count remains empty

My webhost is using PHP 5.2.11 and MySQL 5.0.91. I've set WAMPServer to reflect PHP 5.2.9-2 and MySQL 5.0.88. Like I said earlier, this works for locahost. If I paste the select statement into mysqladmin like:

SELECT COUNT( * ) AS count FROM command WHERE ISIC = '39791';

I get a count of 5 which is as it should be. I'm thinking the problem might be with my isp but am not sure.
