**melodicsounds**Hi,

In my form: https://www.jotform.com/build/80248892549874

I have some fields that I need to add the correct format for the decimals. I am talking about "Extra cost, sub total, iva and total" fields. This has the correct format as the default imput but when the operations are made the format of the numbers is:

Ex: 200,00 and I need to be 2,000

Can you help me?
