Please help! "Parse error on line 372"

Hey I downloaded a tag cloud gadet, and my site stopped working. it keeps throwing up this error:

Parse error: syntax error, unexpected ‘<‘ in public_html/itchyimagination.com/wp-content/themes/i-excel/functions.php on line 372

Line 372 doesn’t have anything on it, and I have not edited the code in any way, because I am a PHP n00b!!! it is the exactly the same as the file in the theme’s zip folder.

below I have pastsed a copy of the section of code where I presume the error is.

function iexcel_post_nav() {
	global $post;	

	// Don't print empty markup if there's nowhere to navigate.
	$previous = ( is_attachment() ) ? get_post( $post->post_parent ) : get_adjacent_post( false, '', true );
	$next     = get_adjacent_post( false, '', false );	

	if ( ! $next && ! $previous )
		return;
	?>
	<nav class="navigation post-navigation" role="navigation">
		<h1 class="screen-reader-text"><?php _e( 'Post navigation', 'i-excel' ); ?></h1>
		<div class="nav-links">

		</div><!-- .nav-links -->
	</nav><!-- .navigation -->
	<?php
}
endif;
=============LINE 372 IS HERE==========================	

// Add specific CSS class by filter

if anyone could help me out, I would super appreciate it!!
