after login

i have set cookies after user login and get their login info.....
then i have a function that user can update their data.....
but i failed to do that......
i have use cookies and get user info from database......but when user update their info......database is still the old info.....it didnt change anything,

the code is like that:
note: "visitor" is cookies as user login email

<?

if ($visitor){
mysql_connect("localhost", "root");
mysql_select_db("applicant") ;
$result = mysql_query("select * from applicant_profile where ae_mail='$visitor'");

if ($Submit){

if ($password==$confirm){

$sql = "UPDATE applicant_profile SET a_password='$password',
a_name='$name', a_address='$address', a_phone='$phone',
a_salary='$salary' , WHERE ae_mail=$email";

$result = mysql_query($sql);

?>

<h3> successfuly update </h3>
<?php
}
else
{
echo"password mismatch";

}

}
} ?>

are you resetting the cookies after they update their info?

how it resetting? what i need to do and get the cookies again?

its not to do with cookies

your query had an error in it, try this instead

$sql = "UPDATE applicant_profile SET a_password='$password',
a_name='$name', a_address='$address', a_phone='$phone',
a_salary='$salary' WHERE ae_mail=$email";

i already del the comma, also cannot worked it.....i already spend a lot of time debug it, still can't get this......anybody help me?
