 * Default sign-up form has fields added eg
    <input type=”hidden” name=”INTERESTS[
   398247293874]” value=”On”> which works in [mc4wp_form id=”27458″]
 * But using [mc4wp_checkbox “Subscribe to our newsletter?”] these aren’t used.

 * Hey [@funsail](https://wordpress.org/support/users/funsail/),
 * Can you please try changing the above code with below and let us know if that
   works?
 * `<input type="hidden" name="MC4WP-INTERESTS[398247293874]" value="On">`
 * Also, please generate the code again using our form to make sure the value matches
   your MailChimp list.

 * No doesn’t make any difference.
    Do you understand what I mean? It’s only not
   working in the Contact7 forms. It’s not injecting any code at all
 * <span class=”mc4wp-checkbox mc4wp-checkbox-contact-form-7″><label><input name
   =”_mc4wp_subscribe_contact-form-7″ value=”1″ checked=”checked” type=”checkbox”
   ><span>Sign up</span></label></span>

 * Hello,
 * Please note that our shortcode for CF7, does not add any additional code. You
   will need to copy the code from our forms and add it to your CF7 or any other
   custom form you might be using.
 * I hope I have explained better.
