Product detail page not showing variants as well as cart button not working

Hello,

My shopify product has variants added from backend [ https://6af8198x7q8a6d2w-5090617.shopifypreview.com/products/who-is-allah-swt ] but isn’t showing on front end, select box showing display: none and when change it to block its not changing variant price, image etc.

Also the add to cart button isn’t working.

Below is the code:

{% assign selectedVariant = product.selected_or_first_available_variant | default: product.variants.first %}
{% capture productGoalDeliveryDate %}{{ settings.product-sale-goal-estimated-delivery-date | trim }}{% endcapture %}

.add-to-cart-button:hover{ color: #fff !important; } span.lable { color: #fd8311; font-size: 19px; } a.a_bundled { display: block; color: #fff; background: red; font-weight: 700; font-size: 22px; border-radius: 23px; margin-top: 10px; padding: 2px 8px; width: 123px; }
{% include 'breadcrumbs' %}

{{ product.title }}

{{ selectedVariant.price | money }} {% unless product.variants.size == 1 and product.compare_at_price_min <= selectedVariant.price %} {% if selectedVariant.compare_at_price > selectedVariant.price %}{{ selectedVariant.compare_at_price | money }}{% endif %} {% if selectedVariant.compare_at_price > selectedVariant.price %} {{ "products.product.saving" | t }} {{ selectedVariant.compare_at_price | minus: selectedVariant.price | money }} {% endif %} {% endunless %}
{% assign featured_image = selectedVariant.featured_image | default: product.featured_image %}
