Please help with css selection code1 :D

I’m not a coder at all, but I can figure out what’s going on for the most part.

I’m trying to get soem code working that will choose a certain layout for a particular category of posts (my photo blob – category-9).

I am using the Arras theme, and I think I’ve located the section of code that selects the layouts and stylesheets. I’ve tried to insert code that I found here, on WordPress, that will choose a specific layout for a given category. I’m just not sure of syntax since I am not a coder (keep getting syntax errors in Dreamweaver).

Here is the code:

function arras_add_layout_css() {
	global $arras_registered_alt_layouts;

	if ( count($arras_registered_alt_layouts) > 0 ) {

		if ( defined('ARRAS_FORCE_LAYOUT') ) {
			$layout = ARRAS_FORCE_LAYOUT;
		}
		else
	    {
		if ( is_category('9') ) { // Load special CSS for "Photo Blog" category 
		{
 			?><link rel="stylesheet" href="<?php bloginfo('template_url'); ?>/category-9.css" type="text/css" media="screen" />;
	 		}
            else
        	{
   			<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" media="screen" />
			<?php } ?>
			} else {
			$layout = arras_get_option('layout');
		}

		?><link rel="stylesheet" href="<?php bloginfo('template_url') ?>/css/layouts/<?php echo $layout ?>.css" type="text/css" /><?php
	}
}
