Help needed! Adding code in functions.php is breaking my site!

Hi guys,

I’m fairly new to php and am trying to add a theme options page to my custom theme. I found some excellent tutorials online and one in particular that works well. When i add the code from the example to my existing functions.php file the the theme options page in the admin area breaks down to a black white page indicating and error. The problem is with the php syntax in the code but i can’t quite figure out what needs to be done in order to make it work. Can anyone help to combine the 2 following bits of code into one functions file?

Thanks.

Existing functions code…

<?php

//Navigation Menus

add_action( 'init', 'register_my_menus' );

function register_my_menus() {
register_nav_menus(
array(
'home' => __( 'Home' )
)
);

}

?>

And the code i want to add..

<?php

require_once ( get_stylesheet_directory() . '/theme-options.php' );

function sa_layout_view() {
	global $sa_options;
	$settings = get_option( 'sa_options', $sa_options );
	if( $settings['layout_view'] == 'fluid' ) : ?>
<style type="text/css">
#wrapper {
	width: 94%;
	max-width:1140px;
	min-width:940px;
}
#branding, #branding img, #access, #main, #colophon {
	width:100%;
}
</style>
	<?php endif;
}

add_action( 'wp_head', 'sa_layout_view' );
