ช่วยดูโค๊ดของผมหน่อยครับเกี่ยวกับการส่งค่าผ่าน url ไม่รู้ว่ามันผิดตรงไหนแสดงไม่ขึ้นใน Excel ครับ

        $time = $_POST['time'];
	$time2 = $_POST['time2'];
	$person = $_POST['person'];
	
if(isset($_POST[search1])){
		$strSQL = "SELECT acc_monitor_log.pin,DATE(acc_monitor_log.time) AS MonitorDate, 
	IF(MIN(TIME(acc_monitor_log.time)) < '13:00:00',MIN(TIME(acc_monitor_log.time)),'Pending...') AS TimeIn,
	MAX(TIME(acc_monitor_log.time)) AS TimeOut,
	userinfo.name,userinfo.lastname FROM acc_monitor_log,userinfo
WHERE acc_monitor_log.pin = userinfo.badgenumber AND acc_monitor_log.door_id = 6 AND acc_monitor_log.verified NOT LIKE '%200%'AND DATE(acc_monitor_log.time) LIKE '$time1%' AND acc_monitor_log.pin LIKE '%$person2%'
GROUP BY acc_monitor_log.pin, MonitorDate, userinfo.name, userinfo.lastname ORDER BY MonitorDate, acc_monitor_log.pin ";
	$objQuery = mysql_query($strSQL) or die(mysql_error());
	$Num_Rows = mysql_num_rows($objQuery);
	}

<div id="left"><a href="1234.php?timein=<?=$Result["TimeIn"];?>&timeout=<?=$Result["TimeOut"];?>
    &person=<?=$Result["pin"];?>" target="new"><b>Export To Excel</b></a>

if(isset($_POST['search']) || isset($_POST['search1'])){
			$i=1;	
			while($Result = mysql_fetch_array($objQuery))
{
  ?>
