Why is my add to cart button missing after changing themes?

[starspears]

Hi, I recently changed the theme to my store to the boundless theme. But I do not have the add to cart button. How can I add it? I've tried adding it to the codes but it's not working.

Add this to product-grid-item-liquid: 

(Remove the third line if you don't want the quantity field to show)

<form method="post" action="/cart/add">
  <input type="hidden" name="id" value="{{ product.variants.first.id }}" />
  <input min="1" type="number" id="quantity" name="quantity" value="1"/>
  <input type="submit" value="Add to cart" class="btn" />
</form>

 Add this to theme.scss.liquid to center it:

.add-to-cart{
text-align: center;
}
