or die ( 'Unable to select the data from inventory.' );
if ( $result1 )

//change the status of the inventory item in inventory table
$sql2="UPDATE inventory SET inv_status="assigned" where
inv_tag='$inv_tag' "; // This is line number 29.
$result2 = mysql_query( $sql2 )
or die ( 'Unable to execute query for upadation of inventory
