Problems with wp_localize_script & jquery

[wellyfish]

Trying to build in an ajax function that will update_post_meta.

Got this (amongst other js which works just fine) in my js file:

	$('.closetask').click(function()
		{
			var thisid = $(this).attr("id");
			console.log(thisid);
			var splitx=thisid.split("-");
			var target=splitx[1];
			var post_meta = "XXXX";
				console.log(target);
		
			$.ajax({
				type: "post",
				url: ajax_vars.url,
				data: "action=post-like&nonce="+ajax_vars.nonce+"&post_like=&post_id="+target,
				success: function(count)
					{
						if(count != "already")
							{
								heart.addClass("voted");
								heart.siblings(".count").text(count);
							}
					}
				});
		});

Got this in my functions.php file:

function mytheme_wp_enqueue_scripts() {
//  wp_enqueue_script('jquery');
wp_enqueue_script('funcs', get_bloginfo('stylesheet_directory') . '/funcs.js', array('jquery'));
wp_localize_script('funcs', 'ajax_vars', 
			array(
						'url' => admin_url('admin-ajax.php'),
						'nonce' => wp_create_nonce('ajax-nonce')
					));
}

add_action( 'wp_enqueue_scripts', 'mytheme_wp_enqueue_scripts' );

problem is, when the click event fires I get this message in firebug:

ReferenceError: ajax_vars is not defined
[Break On This Error]

url: ajax_vars.url,

So it seems as though it's not picking up the ajax_vars array in the wp_localize_script in the functions file.

Anyone know what I'm doing wrong?
