code for adding Jquery plugin

Hi all,

I’ve been trying to get a query plugin to work on my WordPress site. It’s not though and I’m hoping someone could tell me what I’m doing wrong…
I went about as following:

First I put the files

curtain.js
curtain.css
scripts.js

in a js folder, which I put in my theme folder. I am using a child theme!

I then put the following code in the functions.php of my child theme.

function my_scripts_method() {
if (!is_admin()) {
wp_register_script( ‘curtain’, get_stylesheet_directory_uri() . ‘/js/curtain.js’, array( ‘jquery’ ) );
wp_register_script( ‘scripts’, get_stylesheet_directory_uri() . ‘/js/scripts.js’, array( ‘jquery’ ) );
wp_enqueue_script(‘curtain’);
wp_enqueue_script(‘scripts’);
wp_enqueue_script(‘jquery’);
}

add_action(‘wp_enqueue_scripts’, ‘my_scripts_method’);

..then this code in the scripts.js:

$(document).ready(function(){
$(‘.curtains’).curtain();

});

I now just see the actual code on my front page and I get the following message (amongst others):

Warning: Cannot modify header information – headers already sent by (output started at /data/home/stat01/domains/statesofgrace.nl/public_html/wp-content/themes/weaver-ii-child-demo/functions.php:4) in /data/home/stat01/domains/statesofgrace.nl/public_html/wp-login.php on line 368

What’s going wrong here??

Thanks in advance…

Hans
