Custom taxonomies in theme option page.

I have created a custom taxonomy called ‘genre’. I have terms like scifi, Comedy, Drama , action etc, under this ‘genre’ taxonomy.

I am trying to make a custom taxonomy selection option in my theme option page so that I can query post with any specific term in that custom taxonomy. I have been trying to get this done using the get_terms function.

The code I came up with is this,

$zm_terms_obj = get_terms('genre') ;//genre is the name of my custom taxonomy
$zm_terms = array();
foreach ($zm_terms_obj as $zm_term) {
$zm_terms[$zm_term->term_id]=$zm_term->name;
}
$terms_tmp = array_unshift( $zm_terms, "Select a genre:");

and for option

array( "name" => "Movie Genre",
	"desc" => "",
	"id" => $shortname."_mgenre",
	"std" => "Select a genre:",
	"type" => "select",
	"options" => $zm_terms),

Now when I go to the theme option page and try to select a genre it is supposed to list options like scifi, comedy, drama, action. But I find the select field blank. No terms are listed.

Anyone else facing a similar issue? and any suggestions are most welcome.
