Formiantor forms to testimonail

I wanted to created a widget that pulls data submited in forminator through a specific form but the code i have is not working i need some help to find where i could be wrong

here is the code i have:

<?php
// Register shortcode for custom testimonial widget
define('FORMINATOR_FORM_ID', 7673);

add_shortcode('custom_testimonial_widget', function () {
global $wpdb;

// Define Forminator tables
$entry_table = $wpdb->prefix . 'frmt_form_entry';
$meta_table = $wpdb->prefix . 'frmt_form_entry_meta';

// Fetch the latest 5 entries for the specified form ID
$entries = $wpdb->get_results($wpdb->prepare(
    "SELECT 
        em1.meta_value AS name,
        em2.meta_value AS designation,
        em3.meta_value AS review,
        em4.meta_value AS image_url
    FROM {$entry_table} e
    INNER JOIN {$meta_table} em1 ON e.id = em1.entry_id
    INNER JOIN {$meta_table} em2 ON e.id = em2.entry_id
    INNER JOIN {$meta_table} em3 ON e.id = em3.entry_id
    INNER JOIN {$meta_table} em4 ON e.id = em4.entry_id
    WHERE e.form_id = %d
      AND em1.meta_key = 'name-1'
      AND em2.meta_key = 'text-1'
      AND em3.meta_key = 'textarea-1'
      AND em4.meta_key = 'upload-1'
    ORDER BY e.id DESC
    LIMIT 5",
    FORMINATOR_FORM_ID
));

// If no entries found, display a message
if (empty($entries)) {
    return '<p>No testimonials found for this form.</p>';
}

// Render the testimonials in a slider
ob_start();
?>
<div class="custom-testimonial-slider">
    <?php foreach ($entries as $entry): ?>
        <div class="testimonial-item">
