Unfortunately, you wont be able to add any additional field in the payment integration and the amount can't be changed based on date.
Please let us know if you need further assistance.
Do you have another solutions??
Maybe something like: totalsum + 5 days x 10% =
Hi Eddy, we do apologize but the ability to do full mathematical calculations on our forms is still somewhat limited however, I would be happy to add your vote to our Features Request List for this.
It might be possible to come up with a custom workaround solution for this in the time being using the form's source code and some additional customized programming but it will take some time to try to figure out and if we are successful one of us will update you as soon as we can about it.
