Testing Adobe Sign and Formatting numerical values for currencies

Hello
I am creating format templates for Adobe Sign with form fields to be calculated.
Here I have 2 big challenges:
- How can I test the form WITHOUT having to send it as agreements?
- Formatting numerical values for currencies: I need 2 decimal places, even if the 2nd decimal place is a zero.
In the preview this is shown to me, but in the sent document this 2nd decimal place is suppressed.

Does anyone have a suggestion for a solution?

Thank you
Cate
