IE conditional help

I’m using a TwentyTen child theme and need to add a conditional for IE. This is what I have in my header

<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 'stylesheet_url' ); ?>" />
<!--[if IE]>
<link rel="stylesheet" href="<?php bloginfo('template_directory'); ?>/ie.css" media="screen" type="text/css" />
<![endif]-->

I’ve added #wrapper {border:5px solid #000;} to the ie.css stylesheet just to see if it would show up, but it doesn’t seem to be working.
Anyone see what I’ve done wrong?

**nvm, figured it out 2 seconds after posting this, needs to be stylesheet_directory with a child theme.
