<td width="60" bgcolor="#FFFFFF"><div align="center">
						<?php
								$sql_500140A01 = "SELECT COUNT(barcode) FROM barcode_demo WHERE address = '500140'";					
								$sql_500140A01 .= " AND Barcode  LIKE 'A01%'";
								$qr_500140A01 = mysql_query($sql_500140A01) or die ("Error Query [".$sql_500140A01."]");
								$fetch_500140A01 = mysql_fetch_assoc($qr_500140A01);
								echo $fetch_500140A01["COUNT(barcode)"];
						?>
