JavaScript Not Working Properly

Hello, I’m having issues with JavaScript working on my website. On my static website, when you click “Design” or “Illustration”, the objects move around, but on the WordPress site, the objects don’t. I’ve been trying everything, from forcing jQuery to an older version, to checking the order JavaScripts are being applied.

I’m at a total loss. :\

Here’s the static site of how it is supposed to work:
http://rrzart.com/static/portfolio.html

here is my WordPress site thus far:

http://rrzart.com/portfolio/

Here is my functions.php so far:

<?php

function wpt_theme_styles() {

	wp_enqueue_style( 'normalize', get_template_directory_uri() . '/css/normalize.css' );
	wp_enqueue_style( 'grid', get_template_directory_uri() . '/css/grid.css' );
	wp_enqueue_style( 'headerstyle', get_template_directory_uri() . '/css/headerstyle.css' );
	wp_enqueue_style( 'headerstyleie', get_template_directory_uri() . '/css/headerstyleie.css' );
	wp_enqueue_style( 'main', get_template_directory_uri() . '/style.css' );
}

add_action( 'wp_enqueue_scripts', 'wpt_theme_styles' );

//Making jQuery Google API

function modify_jquery() {

    if (!is_admin()) {

        // comment out the next two lines to load the local copy of jQuery

        wp_deregister_script('jquery');

        wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.js', false, '1.8.1');

        wp_enqueue_script('jquery');

    }

}

add_action('init', 'modify_jquery');

function wpt_theme_js() {

  wp_register_script( 'responsive-nav', get_template_directory_uri() . '/js/responsive-nav.js', false );
  wp_register_script( 'jquery-isotopemin', get_template_directory_uri() . '/js/jquery.isotope.min.js', array('jquery'), false );
wp_register_script( 'fastclick', get_template_directory_uri() . '/js/fastclick.js', '1.0', true );
  wp_register_script( 'scroll', get_template_directory_uri() . '/js/scroll.js', '1.0', true );
  wp_register_script( 'fixed-responsivenav', get_template_directory_uri() . '/js/fixed-responsive-nav.js', '1.0', true );
  wp_register_script( 'app', get_template_directory_uri() . '/js/app.js', '1.0', true );

	wp_enqueue_script( 'responsive-nav', get_template_directory_uri() . '/js/responsive-nav.js', '', '', false );
	wp_enqueue_script( 'jquery-isotopemin', get_template_directory_uri() . '/js/jquery.isotope.min.js', array(jquery), '', false );
	wp_enqueue_script( 'fastclick', get_template_directory_uri() . '/js/fastclick.js', '', '', true );
	wp_enqueue_script( 'scroll', get_template_directory_uri() . '/js/scroll.js', '', '', true );

	wp_enqueue_script( 'fixed-responsivenav', get_template_directory_uri() . '/js/fixed-responsive-nav.js', '', '', true );
	wp_enqueue_script( 'app', get_template_directory_uri() . '/js/app.js', '', '', true );
}

add_action ( 'wp_enqueue_scripts', 'wpt_theme_js' );

?>

Thanks for any help!
