hello, i create Klaviyo form on my website, 

<form id="email_signup" class="w-full klaviyo_gdpr_embed_TULjq2" action="//manage.kmail-lists.com/subscriptions/subscribe" data-ajax-submit="//manage.kmail-lists.com/ajax/subscriptions/subscribe" method="GET" target="_blank" novalidate="novalidate">

                    <div class="flex justify-center items-center">

                        <h1 class="text-center w-full lg:w-8/12 mb-8 lg:mb-16 font-bold text-lg lg:text-4xl">Where should we send your results? Enter your email address:</h1>

                    </div>

                    <div class="flex justify-center items-center klaviyo_field_group">

                        <input type="hidden" name="g" value="TULjq2">

                        <input type="hidden" name="$fields" value="$consent">

                        <input type="hidden" name="$list_fields" value="$consent">

                        <input type="email" value="" name="email" id="k_id_email" placeholder="name@email.com" class="w-full placeholder-black placeholder:text-"#8D7B68] font-bold !text-base lg:!text-xl !rounded-lg !bg-c#e6e6e6] !border-2 !border-e#7B7B7B] btn-box-shadow !p-6 outline-0" />

                        <div class="klaviyo_field_group klaviyo_form_actions hidden">

                            <input type="checkbox" name="$consent" id="consent-email" value="email" checked>

                            <input type="checkbox" name="$consent" id="consent-web" value="web" checked>

                        </div>

                    </div>

                    <div class="flex justify-center items-center klaviyo_form_actions">

                        <button class="klaviyo_submit_button bg- #4AB45A] w-full lg:w-4/12 btn-box-shadow rounded-xl font-bold text-sm lg:text-2xl w-full py-4 text-white mt-8 lg:mt-12">Submit</button>

                    </div>

                    </form>

and the scripts

<script type="text/javascript" src="//www.klaviyo.com/media/js/public/klaviyo_subscribe.js"></script>

  <script type="text/javascript">

    KlaviyoSubscribe.attachToForms('#email_signup', {

      hide_form_on_success: true,

      success_url: "https://tryoxgn.com/results/",

      extra_properties: {

        $source: '$embed',

        $method_type: "Klaviyo Form",

        $method_id: 'embed',

        $consent_version: 'Embed default text'

      }

    });

  </script>

it was working fine, but i needed to create new sign up form, and when i create new form with embed and email options and save it and change form ID and try to submit form i always get same error 
List does not exist.

why is that?
