Populate info in payment tool total based on form field selections

I have a signup form where I ask parents to specify the amount of children they want to signup for a kids club. Parents have to enter additional info based on each quantity kids they sign up. For example, if a parent has 2 kids and orders 2 subscriptions, they must enter information for each child. In addition to this, I want the order "Total" to be updated based on the quantity of children selected earlier in the form.

Is there a way to accomplish this without using the "Collect Donations/Custom Amount Payments" option in the payment tools? I want to use the "Sell Products" option and have the option to add a coupon code.

Hi,

Thank you for contacting us.

Unfortunately, there is no way to do what you are requesting, it's not possible to populate a payment field if you are using the integration to sell products or subscriptions, you can add the quantity field, but you can not populate it, to add the quantity field, you can follow this guide :
