Redirection after submitting Jetpack Contact Form

Hi:

Using most recent version of WP.

This thread is closed but I had another question for it: https://wordpress.org/support/topic/jetpack-redirect-after-contact-module-submition/

It’s explaining how to “redirect after form submission” as noted on THIS page: https://jetpack.com/support/contact-form/advanced-customization/

I am trying to redirect from the form on this page (https://www3.theampersandgroup.com/contact/) to this page after people submit the form: https://www3.theampersandgroup.com/guide/

I’d actually like to be able to redirect directly to the pdf that is ON that page but I don’t think that’s possible, is it? That link would be to https://www3.theampersandgroup.com/wp-content/uploads/2020/01/Ampersand-Resource-Guide-2020.pdf

So I only have one form on the site, and it is contact-form-17

So I tried this code:

$redirects = array(
        '17' => home_url( 'https://www3.theampersandgroup.com/guide/' ),
    );

I entered this in code snippets:

/**
 * Jetpack Contact Form Custom Redirections.
 *
 * @param string $redirect Post submission URL.
 * @param int $id Contact Form ID.
 * @param int $post_id Post ID.
 *
 * @return string $redirect Custom Post submission URL.
 */
function jetpackcom_custom_form_redirect( $redirect, $id, $post_id ) {
    /**
     * Create a list of pages where you've inserted forms.
     * For each contact Form ID (found via the id attribute on the form),
     * set up a custom URL where the user will be redirected.
     */
    $redirects = array(
        '17' => home_url( 'https://www3.theampersandgroup.com/guide/' ),
    );
   
    // Let's loop though each custom redirect.
    foreach ( $redirects as $origin => $destination ) {
        if ( $id == $origin ) {
            return $destination;
        }
    }
   
    // Default Redirect for all the other forms.
    return $redirect;
}
 
add_filter( 'grunion_contact_form_redirect_url', 'jetpackcom_custom_form_redirect', 10, 3 );

I saved this in code snippets. I didn’t know whether to change the default of: Run Everywhere, Run only in Admin, Run only on Front-end, Only run once from “Run Everywhere” to admin or front end – tried it with “Run Everywhere” and “Run only on front-end” and both gave me this error message after I submitted the form:

Forbidden

You don’t have permission to access this resource.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.`

So I don’t know what I’m doing wrong – is there something else I need to change? Do I just enter the destination page as:/guide/ instead of the entire url?

Help greatly appreciated.
