[fw-mvc] problem with zend_formElemend_Select

Hello overyone.

I'm trying to fill a  Zend_Form_Element_Select box with an array but it stays empty on the screen.

This is my code:

// create artist name text field

$artistNameElement = new Zend_Form_Element_Text('artistName');

$artistNameElement->setLabel("Artist name: ");

$genres = array("multiOptions" => array(

"electronic" =>"Electronic", 

"country" => "Country",

"rock" =>"Rock", 

"r_n_b" =>"R & B", 

"hip_hop" => "Hip-Hop",

"heavy_metal" =>"Heavy-Metal",

"alternative_rock" =>"Alternative Rock", 

"jazz" =>"Jazz", 

"pop" =>"Pop"

));

$genreElement = new Zend_Form_Element_Select('genre', $genres);

$genreElement->setLabel("Genre:");

$genreElement->setRequired(true);

What is going wrong?

Thanks,

j sanders
