Start by echoing out your $query just before the mysql_query statement, so you can check that it’s what you expect.
Then put some error handling in your code to identify if there’s a database error being returned:

$query="SELECT * FROM members where username = '$username'";
echo $query.'<br />';
$result=mysql_query($query); 
if (!$result) {
    die('Error executing query: ' . mysql_errno().' '.mysql_error());
}
$num=mysql_numrows($result); 

These are absolute basics that you should always be doing before asking for help.

Also, try escaping $username before using it in your query
