Jason, I think I'm getting out of my depth. So if I have say twenty fields, I have to manually add the 'isset' part at the beginning and a few commas, brackets at the end of each input field.
What is the difference between:
<?php echo(ValidatedField("inserttest_365","f_name")) ?>
<?php echo((isset($_GET["invalid"])?ValidatedField("usersinsert","UserFirstName"):"" )); ?>
