wp_menu in wordpress php function - php

Question

I'm trying to create a simple nav in wordpress, however the wp_nav_menu parameters are ignored , am I missing something obvious?
I'm using a blank template called html5 blank. The Steps i've taken so are listed below
1) Register the menu in functions.php
2) From word press back end Create a menu called 'p' and assign pages
3) Give the menu a theme location
Registering and assigning menu location work fine , some but for some reason the wp_ parameters are ignored EG container , menu class, menu id etc...
If i inspect element, the container 'nav' is missing and the li items have default word press classes
BELOW is my code
Code in header.php
<?php html5blank_nav() ?>
Code in functions.php
function html5blank_nav()
{
wp_nav_menu(
array(
'theme_location' => 'primary pete',
'menu' => 'p'
'container' => 'nav',
'container_class' => '',
'container_id' => '',
'menu_class' => 'slimmenu',
'menu_id' => 'navigation',
'echo' => true,
'fallback_cb' => 'false',
'before' => '',
'after' => '',
'link_before' => '',
'link_after' => '',
'items_wrap' => '<ul>%3$s</ul>',
'depth' => 0,
'walker' => ''
)
);
}
// Register HTML5 Blank Navigation
function register_html5_menu()
{
register_nav_menus(array( // Using array to specify more menus if needed
'primary' => __('primary pete', 'Primary Menu'),
'sidebar-menu' => __('Sidebar Menu', 'html5blank'),
'extra-menu' => __('Extra Menu', 'html5blank')
));
}
// Remove the <div> surrounding the dynamic navigation to cleanup markup
function my_wp_nav_menu_args($args = '')
{
$args['container'] = false;
return $args;
}
// Remove Injected classes, ID's and Page ID's from Navigation <li> items
function my_css_attributes_filter($var)
{
return is_array($var) ? array() : '';
}
// Remove invalid rel attribute values in the categorylist
function remove_category_rel_from_category_list($thelist)
{
return str_replace('rel="category tag"', 'rel="tag"', $thelist);
}
// Add page slug to body class, love this - Credit: Starkers Wordpress Theme
function add_slug_to_body_class($classes)
{
global $post;
if (is_home()) {
$key = array_search('blog', $classes);
if ($key > -1) {
unset($classes[$key]);
}
} elseif (is_page()) {
$classes[] = sanitize_html_class($post->post_name);
} elseif (is_singular()) {
$classes[] = sanitize_html_class($post->post_name);
}
return $classes;
}
Many thanks,

When i try to reproduce this the menu with container_class => 'slimmenu' is shown.
Are you sure when you add a class to the container_class parameter this is not shown in the inspector?
Also noticed a missing comma after the parameter 'p' when i copied your code. But i don't think it will resolve your problem.
