Ecommerce Show Subtotal in Cart Button

Hey, all –

Is there a way to add the subtotal to the cart button that is in the navigation? In this tutorial by Webflow it shows you can but the video appears old and the settings no longer match what I see in my site. There’s no way to add a text block and link it to cart subtotal.

Thanks!
Adam
