wp_enqueue_script should be used with the file URL, not the PATH. Here’s what I use in my functions.php:
# Template Location
define('THEME', get_bloginfo('template_url'), true);
# CSS files location
define('THEME_CSS', THEME . '/style', true);
# JS files location
define('THEME_JS', THEME . '/script', true);
# Enqueue JS
function mytheme_js() {
if (is_admin()) return;
wp_enqueue_script('jCycle', THEME_JS . '/jquery_cycle.js', 'jquery');
wp_enqueue_script('myScript', THEME_JS . '/myScript.js', 'jquery');
}
add_action('init', mytheme);
