Hiding Static Front Page Menu

Hi – I’m creating a static front page that will allow viewers to choose between three paths – portfolios, workshops and blog; I want to hide the navigational menu on this page. I found this code by looking into the forums but it returns a blank white page in browser. If I don’t have this code in my header.php file, the page shows fine but with menus. What can I change here to have just the menu bar hidden from view?
This gives a blank page for me (when I entered my page name which is Home2, in place of front_page…

<?php if ( is_front_page() ) {
echo ‘Foo’;
}
else
{
wp_nav_menu( array( ‘theme_location’ => ‘primary’ ) );
}
?>
