Hi Meltem,
the second one was a better description of your problem.
Attached is the most convenient approach can come up with for
this problem. It is not optimized, but should be easy to
understand.

<?php
$submitted = isset($_REQUEST['a']); // submitting data or just
retrieving page?
if($submitted) $fields_complete = ($_REQUEST['a'] &&
$_REQUEST['b'] && $_REQUEST['c']); // are all fields filled?
if(!$submitted) {
$f_a_def = "";
$f_a_err = "";
$f_b_def = "";
$f_b_err = "";
$f_c_def = "";
$f_c_err = "";
};
if($submitted && !$fields_complete) {
if($_REQUEST['a']) { $f_a_def = $_REQUEST['a']; $f_a_err = "";}
else { $f_a_def = ""; $f_a_err = "you forgot to fill this field";};
if($_REQUEST['b']) { $f_b_def = $_REQUEST['b']; $f_b_err = "";}
else { $f_b_def = ""; $f_b_err = "you forgot to fill this field";};
if($_REQUEST['c']) { $f_c_def = $_REQUEST['c']; $f_c_err = "";}
else { $f_c_def = ""; $f_c_err = "you forgot to fill this field";};
};
if(!$submitted || !$fields_complete) {
echo ('
