Reply To: additional bookings

That won’t be easy. At the point when adding a new reservation the only thing the script knows about the price Fields of the first reservations is the sum of all. And as the form isn’t the same anymore you can’t get these data from there.
So you’ll have to add a new variable that stores this informations, a function to read that variable and generating the display from that. Form.js is the right file for all of that.
