Adding a custom "our choice" badge on products

Site URL: http://www.legionparis.com

Hello,

I've scrolled along to find a solution to add custom badges like "our choice" or "new" or "unique piece" on my product catalogue. I found what Paul advised here: https://sf.digital/squarespace-solutions/adding-a-custom-product-badge-to-squarespace

But nope, it doesn't work for me. I made everything he told me to do in this article but I never saw any badge on any product... I've begun with the default pre-order badge to be sure it worked before customizing anything but nothing... I'm on 7.0 Brine template west.

Thanks a lot for your precious help!

All the best

Lucie
