The "required" asterisks won't go away without editing a language file (/includes/languages/YOUR_TEMPLATE/english.php); if that file doesn't exist, you'll copy /includes/languages/english.php to that directory and make your edits there. You'll need to change
Code:
define('ENTRY_TELEPHONE_NUMBER_TEXT', '*');
to
Code:
define('ENTRY_TELEPHONE_NUMBER_TEXT', '');
If you're feeling industrious, you could also give a try to the code change I proposed here: http://www.zen-cart.com/showthread.p...required-flags. The most recent code is in the last post of that thread.
