**Chriistian**The masked input widget only allows symbols and the digit 9 as the custom pattern, so you will not be able to use A or B as the pattern. To make the input mask output correctly, you will need to use the following pattern:

**( 9 + 9 = 9 )**You can check out the "Ngân sách từ Địa phương:" field in this form to see it in action: https://form.jotform.com/61748622389972. You can also clone it to your account to see the widget.

**Chriistian**Can you please provide further details regarding your requirement? As of now I believe the Form Calculation widget is suitable for your requirement. It allows you to perform calculations from your fields. To perform these calculations, please follow this guide: How to Perform Calculation in the Form?

Here's a demo form where I add the values from Field A and Field B, then output them in the Form Calculation widget. https://form.jotform.com/61750481467965

If you need further assistance, please let us know.

**FFAV**Hi J,

Maybe is it, However, when i add A AND B output is only "number" while i need unit of money $$$

Ex: 1,200,000 + 1,200,000 = 2,400,000 but output is only "24"

Please, disturb again.

**Charlie**Please note that when you enabled the "Use commas for decimal point", this means that you are using commas for the decimal point. Meaning, 12,000 is actually 12.00 which is 12 when its rounded of as a whole number.

If you use commas for the thousands and millions place, then you need to DISABLE that option.

Your users also do not need to enter commas when doing the calculation, the system understands that 1000 is 1,000 or one thousand.

If you need to add a currency on your total value, simply input it in the form calculation widget. Here an example:

Here's how it looks like:

Let us know if that helps.

**FFAV**Thank for your help! :)) wonderful
