	$objParse1=oci_parse($objConnect,$sql1);
	oci_execute($objParse1,OCI_DEFAULT);	
	echo "<ul>";	
			while($fetcharr1 = oci_fetch_array($objParse1,OCI_BOTH)) {
			$FACULTYID=$fetcharr1['FACULTYID'];
			$FACULTYNAME=$fetcharr1['FACULTYNAME'];
			//echo "<li>$FACULTYNAME</li>";			
			?><li style="color:red;"><? echo $FACULTYNAME ?></li><?
