How to get a value from an array in meta_value

Hi there,

I’ve created a table with combo box in my form of post new item to choose multiple data and save it in meta_value of postmeta table

I want to check if a value is in array of this meta_value, I’ve tried this code but I don’t know the valid syntax:

$univ = array(
		'key' => 'closed',
		'value' => array ("I don'y know what can I put there) ,
		'compare' => 'IN'
);

$prs_string_qu = wp_parse_args($query_string);
$prs_string_qu['meta_query'] = array($univ);
$prs_string_qu['meta_key'] = 'UNIV'; // name of meta_key in my table
$prs_string_qu['orderby'] = 'meta_value';
$prs_string_qu['order'] = 'DESC';

query_posts($prs_string_qu);

// and what can I put there
$term = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );
$term_title = $term->name;

Any help will be appreciated, Thanks in advance
