Basic 13 Discussion (spoilers)

So I was able to complete basic web 13 via the active editing of the code via firebug, however I'm curious as to what I was missing when I downloaded the actual website code and added the "action" to the "post"

<div class="capmain" style="height: 14px;">Basic Web Hacking 13</div>

<div class="main-body">
<center>Login as George!<br>
<br>
<form method="post" action="http://www.hellboundhackers.org/challenges/basic13/index.php">
<select name="name">
   <option value="George">George</option>
</select>

<input value="Log In" name="subname" type="submit">
</form>
</center>

</div>
</div>```

With this submit I was getting the malformed request. Any ideas why? 

Everyone gets that. Its been like that as long as i can remember.
