How can I fix the Lorenza Theme product form error?

So Im trying to implement a notify when available form on the product-form.liquid file but it keeps giving me an error if I remove “{% form ‘product’, product %}” and its corresponding {% endform %} it will work but will mess up the format of the the page and cause the buttons to be close to the text. Please let me know how I can fix this.

Here is the code:

{% form ‘product’, product %}
{% if product.available %} {{ 'products.product.add_to_cart' | t }} {% else %} {{ 'products.product.sold_out' | t }} {% endif %}

{% unless product.available %}

{% comment %} Below is the code for contact me form that appears when the product is sold out {% endcomment %}

{% form ‘contact’ %}
{% if form.posted_successfully? %}

Thanks! We will notify you when this product becomes available!

{% else %}

Notify me when this product is available

{% if customer %} {% else %} {% endif %}
{% endif %}

{% endform %}
{% endunless %}

{% if section.settings.enable_payment_button %}
{{ form | payment_button }}
{% endif %}
{% endform %}
