Hi @pnorbi86
I understand that you’re running into troubles with getting the WooCommerce price fields to work.
This is probably because you’re not using a Shop page. The filters will only typically work when you’re on a shop page or a product category archive.
If you’ve used some custom template to display products in your theme, it might not work.
As an alternative, I’d recommend using Product Blocks built-in to WooCommerce itself. In comes with a slider block as well, which you can try: https://docs.woocommerce.com/document/woocommerce-blocks/
Let us know if you keep running into troubles.
We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
