Functions crashing site

Hi,

This isn't working, any thought?

<?php

// LOAD the THEME CSS

function theme_styles(){

wp_enqueue_style( 'normalize', get_template_directory_uri() . '/css/normalize.css' ); wp_enqueue_style( 'gird', get_template_directory_uri() . '/css/grid.css' ); wp_enqueue_style( 'main', get_template_directory_uri() . '/style.css' ); wp_enqueue_style( 'social', get_template_directory_uri() . '/css/webfonts/ss-social.css' );

wp_register_style( 'flexslider', get_template_directory_uri() . '/css/flexslider.css' ); if(is_page('home')) { wp_enqueue_style ('flexslider'); }

}

// LOAD JS - NOT WORKING!

function theme_js(){

wp_register_script('flexslider', get_template_directory_uri() . '/js/flexslider.js', array('jquery'), '', true);

if(is_page('home')) {
wp_enqueue_script ('flexslider');
}
wp_enqueue_script ('theme.js', get_template_directory_uri() . '/js/theme.js', array('jquery'), '', true););

} add_action('wp_enqueue_scripts', 'theme_js');

add_action('wp_enqueue_scripts', 'theme_styles');

// ENABLE CUSTOM MENUS add_theme_support( 'menus' );

?>
