I tried installing Favicon, deleted a line of code and now have an issue

In the Header.php I tried following some instruction to add a favicon to my site. I accidently deleted the wrong line of code and now have a problem

http://www.fiai.ie/

you’ll see the following line:

>/js/prettyPhoto/css/prettyPhoto.css” title=”prettyPhoto main stylesheet” charset=”utf-8″ />

and I believe this is as I deleted a line of code which was above the following line:

>/js/prettyPhoto/css/prettyPhoto.css” title=”prettyPhoto main stylesheet” charset=”utf-8″ />

<link rel=”stylesheet” href=”<?php bloginfo(‘stylesheet_url’); ?>” type=”text/css” media=”screen” />

Any help is much appriciated.
