Problems with profile tab

Hello,
I have some problems with my code. I have created a custom tab with a html form.
There is the tab but inside there is only the submit button and i don’t see the forms fields.
I tried to assign a dimension but i haven’t resolved the problem.

This is the code:

add_filter('um_profile_tabs', 'add_custom_profile_tab_recensioni_nuova', 1000 );
    function add_custom_profile_tab_recensioni_nuova ( $tabs ) {
        
        $tabs['recensioni_nuova'] = array(
                                     'name' => 'Nuova Recensione',
                                     'icon' => 'um-faicon-comments',
                                     );
        return $tabs;
    }
    
    //Definizione Nuova Recensione//
    add_action('um_profile_content_recensioni_nuova', 'um_profile_content_recensioni_nuova');
    function um_profile_content_recensioni_nuova( $nuova )
    {
        $profile_id = um_profile_id();
        $user_id = get_current_user_id();
        
    echo"
        <form action='invia_nuova.php' method='post'>
        <imput name='scittore' type='hidden' value='$user_id'/>
        <imput name='ricevente' type='hidden' value='$profile_id'/>
        <imput name='punteggio' type='radio' value='1' size='20'/>
        <imput name='punteggio' type='radio' value='2'/>
        <imput name='punteggio' type='radio' value='3'/>
        <imput name='punteggio' type='radio' value='4'/>
        <imput name='punteggio' type='radio' value='5' size='50'/>
        <imput name='descrizione' type='text'/>
        <input type='submit' value='Invia'>
        </form>";
        
        return $nuova;
    }
