# Upsell block adds the product but no cart opens

> The Add button works but nothing opens. Check the cart, then turn on Open cart page or pick your cart app in the block.

The product is most likely in the cart. The **Upsell** block opens a cart only on a set list of themes and cart apps. On anything else it adds the product and nothing opens. Turn on **Open cart page**, or pick your **Cart app**.

## Fix it

1. On your store, click **Add** on an upsell.
2. Open your cart and check the product is there.
3. In Shopify admin, open **Online Store** → **Themes**.
4. Click **Customize** on your theme.
5. Open your product template.
6. Select the **Upsell** block.
7. Pick one fix:
    - **You use Upcart, AMP or Kaching:** set **Cart app** to **Upcart Cart Drawer**, **AMP Drawer** or **Kaching Cart**.
    - **Your theme is on the list but renamed or changed:** turn off **Auto detect theme**, then pick your **Theme type**.
    - **Anything else:** turn on **Open cart page**. Shoppers go to the cart page after **Add**.
8. Click **Save**.

## Themes that open the cart

Dawn, Refresh, Rise, Sense, Taste, Trade, Craft, Spotlight, Studio, Colorblock, Ride, Publisher, Crave, Origin, Digital, Horizon, Savor, Vessel, Ritual, Atelier, Heritage, Dwell, Pitch, Tinker, Fabric, Impulse, Prestige, Symmetry and Broadcast.

Some of these go to the cart page when your theme's cart type is set to page. A live Section Store Cart Drawer opens on any theme, unless its **Open drawer when products are added** setting is off.

## If it doesn't work

- **The button is greyed out:** the product is sold out.
- **The product never reaches the cart:** open the chat bubble in the Section Store app or email help@section.store. Send your theme name, a product URL and the cart apps you use.
