You did not show the message you got, so I'll guess $name=$_POST['search']; does not have a value set. The best way is to use the following construct:

$name = isset($_POST['search']) ? $_POST['search'] : '';

@pritaeas thank you for nyour reply.but when i did what you said it displays "User not found" even if i havent click the search button.what can i do?

[pritaeas]

Your query returns no records, or fails. To check failure do this:

$query = mysql_query ("Select * from confirm_members where email = '$name'") or die(mysql_error());

If it does not fail, check your data.
