Search Not Working

I was messing with my search bar and seemed to have messed it up to where it doesn’t work. I type in a search and it just doesn’t preform the search. Website in question is here.

The current code I have:

<div id="search_box">
    <form method="get" id="search_form" action="<?php bloginfo('url'); ?>/">
        <input type="text" id="s" value="Search" class="swap_value" />
        <input type="image" src="<?php bloginfo('template_directory') ?>/images/go.gif" width="27" height="23" id="go" alt="Search" title="Search" />
		<input type="hidden" id="searchsubmit" value="Search" />
    </form>
</div>
