ขอความช่วยเหลือหน่อยครับ เรื่องการ edit ข้อมูลที่ดึงจาก MySQL มาโชว์ในหน้าเว็บ

		function ListCustomer(SelectValue)
		{
			form1.select2.length = 0
			
			//*** Insert null Default Value ***//
			var myOption = new Option('','') 
			form1.select2.options[form1.select2.length]= myOption
			
			<?
			$intRows = 0;
			$strSQL = "SELECT * FROM `customer_list` ORDER BY cus_id ASC ";
			$objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]");
			$intRows = 0;
			while($objResult = mysql_fetch_array($objQuery))
			{
			$intRows++;
			?>			
				x = <?=$intRows;?>;
				mySubList = new Array();
				
				strGroup = "<?=$objResult["alp_id"];?>";
				strValue = "<?=$objResult["cus_id"];?>";
				strItem = "<?=$objResult["cus_name"];?>";
				mySubList[x,0] = strItem;
				mySubList[x,1] = strGroup;
				mySubList[x,2] = strValue;
				if (mySubList[x,1] == SelectValue){
					var myOption = new Option(mySubList[x,0], mySubList[x,2])  
					form1.select2.options[form1.select2.length]= myOption					
				}
			<?
			}
			?>
