wp_insert_link not working

Question

Im using this code to insert links into my blog:

        $linkdata = array(
             'link_name' => $title,
             'link_url' => $url,
             'link_catetory' => 3, // my cat id
             );

        $link_id = wp_insert_link( $linkdata ); 

Links are inserted, but not in the correct category, I missed something?
