How to connect 2 forms in HTML and Django?

Question

I am creating a web page and i'm wondering if i could make sure that the data on the left is filled before pressing the blue button. On the left you can see a form to pay by entering your address, city etc. but on the right you can see another form with stripe implemented to pay with credit card. I don't know how to get the data from the left and save it in the database so I can create a receipt after successful payment. Here is the code down below.

<div class="container-2">
    <div class="gray-hover">
        <form method="POST">
            <div class="item" id="payment">
                <div class="row">
                    <h4>Možnost nakupa 1: Plačilo po povzetju <small><i>(Za plačevanje s kartico je treba izbrati samo
                                količino in vrsto izdelka!)</i></small></h4>
                    {% csrf_token %}
                    {% if form %}
                    <div class="input-group">
                        <div style="color: red;">{{ form.name.errors }}</div>
                        {{ form.name }}
                    </div>
                    <div class="input-group">
                        <div style="color: red;">{{ form.last_name.errors }}</div>
                        {{ form.last_name }}
                    </div>
                    <div class="input-group">
                        <div style="color: red;">{{ form.street_name.errors }}</div>
                        {{ form.street_name }}
                    </div>
                    <div class="input-group">
                        <div style="color: red;">{{ form.city_name.errors }}</div>
                        {{ form.city_name }}
                    </div>
                    <div class="input-group">
                        <div style="color: red;">{{ form.email.errors }}</div>
                        {{ form.email }}
                    </div>
                    <div class="input-group">
                        <div style="color: red;">{{ form.number.errors }}</div>
                        {{ form.number }}
