I want to make Application Number from various fields.

To my understanding, you are trying to generate an Application Number constructed from the values of different other fields on your form.

If that is the case, may I suggest that you check the instructions in this guide, please?

Hi Mike_G. Thanks For Responding Back. The solution you suggested won't work in my case as I want to manipulate string input and wan.

Let me explain how the Application Number should work.

Suppose someone fills a form with the following details:-

firstName="John";

lastName="Doe";

phoneNumber="1234567890";

// I will Show how I can do this in Java

applicationNumber="A"+String.valueOf(LocalDate.now().getYear()).substring(2)+""+LocalDate.now().getMonthValue()+""+LocalDate.now().getDayOfMonth()+""+firstName.subString(0,1)+""+lastName.subString(0,1)+""+phoneNumber.subString(6);

result of this will be "A210526JD7890"

I want to generate this from 3 fields of the JotForm form i.e. firstName, lastName, and phoneNumber.

How can I accomplish this?

If that is the case, then I would suggest that you check our Substring widget.

https://www.jotform.com/widgets/substring

Reference Guide: How-to-Add-a-Widget-to-your-Form

The widget is used to get part of a string that is a value of another field.

You can also use the widget in conditions to concatenate substrings from different form field values.

Thanks, Mike_G. I was able to achieve what I wanted through your mentioned widget.
