The formula shows as correct, but there is no information displayed, just 0

Hello guys,

So I added these formulas, but when I display the page, it just shows $0, it is not calculating anything. Can anyone help? Thanks.

I think Input subtotal’s value is zero.
But You can debug or inspect (Make sure to have ?debug_mode=true in your URL) to see what’s going wrong over there…

Ok, so I got it to work now, I wasn’t putting the formula in the initial content as well. Thanks a bunch.
