Hi Ivy, thanks for your response. I just wanted to add "Service fee" value to "Total" of Stripe. See screenshot below. I have already defined number values to service fee items and also tired formula but its not adding any number to total other them "my products". Can you please help. 

My stripe integration is connected and i am on "live mode", "sell products" setting.

To add this, you have to make the addition outside the Stripe Widget and pass the total to the payment field. Refer to this guide: How to Pass a Calculation to a Payment Field

Hi Donald, that is another approach i can use but the reason i dont want to use it is:

1. Wont let me add GST in total

2. Stripe wont show price break up (Sub total, GST) in its "total" using "user defined amount".

Can you guide me if its possible use "user defined amount" approach?

This approach worked for me, after adding more field for calculation. Thanks alot for your quick responses, i love jotform. I am going to test it now to see if its recording data properly.

You're welcome!
