my script not running and i need help

P: 20
i have two scripts that are not running to reset a password that has been forgotten and the other to change old password.

here are the scripts.

change_passwd.php
[PHP]
session_start();
do_html_header("Changing password");
//check_valid_user();
$new_passwd=($_POST['new_passwd']);
$new_passwd2=($_POST['new_passwd2']);
if (!filled_out($HTTP_POST_VARS))
{
echo "You have not filled out the form completely.
Please try again.";
display_user_menu();
//do_html_footer();
exit;
}
else
{
if ($new_passwd!=$new_passwd2)
echo "Passwords entered were not the same. Not changed.";
else if (strlen($new_passwd)>16 || strlen($new_passwd)<6)
echo "New password must be between 6 and 16 characters. Try again.";
else
{
// attempt update
if (change_password($valid_user, $old_passwd, $new_passwd))
echo "Password changed.";
else
echo "Password could not be changed.";
}


}
display_user_menu();
//do_html_footer();[/PHP]

error warnings from this code are.

return $word;
}
function reset_password($username)

}

function notify_password($username, $passwd)

if (!($conn = db_connect()))
return false;

else

$email = mysql_result($result, 0, "email");
$from = "From: support@learning_system \r\n";
$mesg = "Your password has been changed to $password \r\n"
."Please change it next time you log in. \r\n";
if (mail($email, "Learning System login information", $mesg, $from))
return true;
else
return false;
}
}[/PHP]

I will try to help here, but I myself am not an expert.

In regards to your dictionary, check your path to make sure that it is indeed there. Since I have not done any php on a Windows box I noticed that you are calling the dictionary with the forward slash /

$HTTP_POST_VARS should be be $_POST

That is all I see right now.

Good Luck

Its true that there is need to check the path but however it seems as if that Windows does not support the dictionary so I'm trying to down it but seems not to be working.I would appreciate if you can help me alternatively to come up with a function that generates a new password.
