Global Shopping Cart Widget

I want to make the shopping cart widget global by placing it in my theme’s header. I tried copying and pasting the shopping cart widget but results in an error. I want to place the shopping cart widget next to my columns at the top.

phleejewelry.com // The website.

<!--HEADER -->
	<div id="header">
		<div id="logo-container"><a href="<?php echo home_url(); ?>"></a></div>
		<?php if(get_opt('_display_tagline')!='off'){ ?>
		<h2 id="site-description"><?php bloginfo( 'description' ); ?></h2>
		<?php } ?>
 		<div id="navigation-container">
 			 <div id="small-res-menu-wraper">
 				<div id="small-res-menu-button"><p href=""><span></span><?php echo pex_text('_menu_text'); ?></p></div>
 			<div id="small-res-menu">
				<?php wp_nav_menu(array('theme_location' => 'pexeto_main_menu', 'fallback_cb'=>'pexeto_no_menu')); ?>
				</div></div>
			<div id="menu-container">
	        	<div id="menu">
				<?php wp_nav_menu(array('theme_location' => 'pexeto_main_menu', 'fallback_cb'=>'pexeto_no_menu')); ?>
				</div>
	        </div>
	        	<?php
			//PRINT THE SOCIABLE ICONS
			if(get_opt('_show_footer_icons')=='on'){
				$icon_links=explode(PEXETO_SEPARATOR, get_option('_icon_links'));
				$icon_imgs=explode(PEXETO_SEPARATOR, get_option('_icon_urls'));
				$icon_titles=explode(PEXETO_SEPARATOR, get_option('_icon_titles'));
				array_pop($icon_links);
				array_pop($icon_imgs);
				array_pop($icon_titles);
				?>
				<div id="header-social-icons"><ul>
				<?php for($i=0; $i<sizeof($icon_links); $i++){
				$title=$icon_titles[$i]?' title="'.$icon_titles[$i].'"':'';
					?>
				<li><a href="<?php echo $icon_links[$i];?>" target="_blank" <?php echo $title; ?>><div><img src="<?php echo $icon_imgs[$i]; ?>" alt="" /></div></a></li>
				<?php } ?>
				</ul></div>
				<?php
			}
			?>

    	</div>
	    <div class="clear"></div>
	    <div id="navigation-line"></div>
	</div> <!-- end #header -->

This is the header code that I’m trying to copy and paste the shopping cart into. How do I go about this? Thanks.
