Remove Secondary Nav from Homepage

Hiya!

I’m trying to remove the Secondary Nav from the homepage only, and running into a dead end.
I had previously swapped the primary and secondary positions so I could customize location better through site:
http://58a.20b.mwp.accessdomain.com/

Here’s the section of code, that I *think* should be working:
// Before Header Wrap
add_action( ‘genesis_before_header’, ‘before_header_wrap’ );
function before_header_wrap() {
echo ‘<div class=”head-wrap”>’;
}

// Reposition the Primary Navigation
remove_action( ‘genesis_after_header’, ‘genesis_do_nav’ ) ;
add_action( ‘genesis_before_header’, ‘genesis_do_nav’ );

// Reposition the Secondary Navigation
remove_action( ‘genesis_after_header’, ‘genesis_do_subnav’ ) ;
add_action( ‘genesis_after_header’, ‘genesis_do_subnav’, 12 );

add_action( ‘get_header’, ‘remove_genesis_do_subnav’ );
function remove_genesis_do_subnav() {
if ( is_home() ) {
remove_action(‘genesis_after_header’, ‘genesis_do_subnav’);
}
}

// After Header Wrap
add_action( ‘genesis_after_header’, ‘after_header_wrap’ );
function after_header_wrap() {
echo ‘</div>’;
}

Any ideas?
Thanks much,
Kate
