WooCommerce order submit button not working

I’m trying to create my first WooCommerce site with Bricks and have immediately come across an issue when trying to test a basic checkout page. In the order summary section, the ‘Sign up now’ button doesn’t work (it should redirect to the payment gateway). This worked before I deleted the Gutenberg checkout template and replaced with a Bricks one.

Probably something really silly - but does anyone know how I can fix this, please? TIA
