# Troubleshoot Product Bundling on Legacy Plans

### About this guide

This guide applies **only** to stores using [**Product Bundling**](/infinite-options/increase-the-cost-of-an-option/product-bundles.md#how-to-set-up-a-product-bundle), the legacy bundling feature in Infinite Options.

If you're using **Native Bundling**, see [**Native Bundling troubleshooting**](/infinite-options/troubleshooting/add-on-product-is-not-working-as-expected.md) instead.

Product Bundling remains available for legacy plans, and many common issues can be resolved by confirming add-on products are active on the Online Store channel or reaching out to support. You can find common reasons for add-ons not to show on the backend of orders below:

#### Before you begin

Before troubleshooting, confirm that your store is using[ **Product Bundling**](/infinite-options/increase-the-cost-of-an-option/moving-from-legacy-to-native-bundling.md#the-difference-of-legacy-vs-native-bundling).

Signs you're using Product Bundling include:

* Add-on products are added to the cart as separate products.
* The bundled product is linked to an Infinite Options option.
* Your store has been using Product Bundling on a legacy Infinite Options plan.

If you're unsure which bundling method you're using, contact our support team.

## Common issues

#### My bundled product isn't being added to the cart

If the bundled product isn't appearing in the cart:

* Verify the bundled product still exists.
* Confirm the product is Active.
* Make sure it's available on the Online Store sales channel.
* Check that the option is still configured to add the correct product.

***

#### Check the product page

From the Infinite Options app, open the product using the **Preview** link.

If you see a **red banner** on the product page, your theme requires additional code for **Product Bundling** and **Required Fields**.

Contact our support team and let us know you see the red banner. We'll install the required code for your theme before continuing with any additional troubleshooting.

####  "Cannot find variant" errors

This error means Shopify can't add the bundled product to the cart.

Check the following:

* Open the bundled product from the Option Set.
* If the preview displays **"Sorry, no products match this option set to preview,"** the original bundled product has been deleted. Update the bundle to use the current product.
* If the product opens successfully, verify that it is **Active** and available on the **Online Store** sales channel.
* Test the product page again after making any changes.

For detailed instructions, see **Resolving "Cannot Find Variant" Errors**.

Here is the full guide: [Solving Cannot Find Variant Errors](#runtime-or-cannot-find-variant-errors)

***

#### The bundled product was deleted

If the bundled product no longer exists and is displayed as a warning on the app dashboard

* Create or restore the product.
* Edit the Product Bundling configuration.
* Select the correct replacement product and variant.
* Test the bundle again.

***

### The wrong product is being added

Review the Product Bundling settings and verify that the option points to the intended product and variant.

***

#### Another app may be interfering

Some apps can interfere with Product Bundling by modifying the cart, preventing more than 1 product from being added to the cart. 

Examples include:

* Cart drawer apps
* Bundle apps
* Subscription apps
* Upsell apps
* Cart customization apps

Temporarily disable the other app or test in a clean theme or product to isolate the issue.

***

#### My option selections aren't appearing

After adding the product to the cart:

* Confirm the bundled product appears.
* Confirm the correct variant was added.
* Confirm the selected options appear as line item properties.
* Place a test order to verify the information carries through checkout.

***

#### Still having trouble?

If you've completed the steps above and Product Bundling still isn't working, contact our support team with:

* Your store URL
* The product you're testing
* The bundled product
* Screenshots or a screen recording
