@joethebaker, it looks like your main menu is in the site-description. Not sure if that was intentional on your part, but in the default theme the main menu has it's own container which only needs to be moved by styling it in your CSS.
<div class="nav-collapse collapse">
<?php wp_nav_menu( array( 'theme_location' => 'main' , 'menu_class' => 'nav' , 'fallback_cb' => array( $this , 'tc_link_to_menu_editor' ), 'walker' => tc__ ( 'header' , 'nav_walker' )) ); ?>
</div><!-- /.nav-collapse collapse -->
Try opening the default copy of the class-header-menu.php file and looking at the arrangements of the div and seeing where the above php code is located.
I used the site-description element to hold my search bar since I'm not using the tagline on my site. (http://www.biologydesign.com/SarahCHanson).
This is the code for the tag-line:
<h2 class="span7 inside site-description"><?php bloginfo( 'description' ); ?></h2>
All you have to do is replace
<?php bloginfo( 'description' ); ?> in the above code with, `<form method="get" id="search_form" action="<?php bloginfo('home'); ?>"/>
<input type="text" class="text" name="s" value="SEARCH" >
<input type="submit" class="submit" value="" />
@mgazzar, my search bar is working fine (just double-checked it), so not sure why yours is not. And just in case, remember, you need to have content to search for.
If you could include a link to your site, then myself and others trying to help you could search for the problem via Firebug.
In the meantime, what file did you put the above code in and is it in your child theme?
