I recently downloaded an app called Section Store which features a lot of apps. I downloaded an app within it called Bundle Builder 3. I’m using it to make a Build a Box page on my website. When I add a bundle to a box, I press Add to Cart nothing gets added. I’m able to add other items on different pages to my cart but I can’t add anything that is connected to the Bundle Builder section.

I thought the reasons are:

  • App Integration Issue: Bundle Builder may not be fully integrated with your theme.
  • JavaScript Errors: Conflicts in JavaScript can prevent the “Add to Cart” button from functioning.
  • Theme Customizations: If your theme has customizations, they may interfere with the app.

And here is a solution: Check for JavaScript errors using Developer Tools (Inspect → Console) on your Build a Box page. If errors appear, it may indicate missing functionality. Test with a default theme to rule out theme customizations. If the problem persists, contact the app’s support team with details and console logs.

Hey Trey!

It’s tough to diagnose the problem without a link to your store.

I suggest emailing the Section Store team at help@section.store — I’m sure they’d be happy to help!

If you’re still exploring solutions, you might want to try Easify Box Builder. It’s a new app we built specifically for bundle use cases like yours.

You can also choose whether to display variants individually or use separate products, apply tiered or fixed discounts, and manage everything from one simple dashboard. Here’s a demo

  • This is the result:

  • This is the app setting:
  1. Create a Box: You can choose either a regular box with total price and discount, or a fixed-price box. In this example, I’m using a regular box with a discount.

  1. In each steps, custom text and add your product

You can set an additional Required Selection to make sure customers must choose exactly one box before moving to the next step.

  1. Set up a discount if needed:

With just 3 simple setup steps, you can create a smooth, engaging experience for your customers—while still keeping full control over pricing, layout, and inventory. The app is 100% free right now, and if you install soon, you’ll become one of our VIP early users who keep it free forever.
