hey guys .. this is my problem .... i've done a page ... index.php and also menu.php ... so .. i include the menu.php in the index.php ... and the index page turned ugly.. but when i preview it .... the page cameout nice.. just as i wanted. later when i remove the <?php include('menu.php'); ?> .at the index.php .... when i refresh dreamweaver says " Making this change would require changing code that is locked by a template or a translator.The change would be discarded" .. so how do i overcome this problem ?
