    How can I add an autoincrement field to my form?

    Asked by yulpark on July 28, 2017 at 02:39 PM

    Hi, 

     

    I am trying to create a form, which will automatically generate a Transaction number but will keep track of last generated number and increase by one. So for example, first submission creates Transaction Number (R100001) then R100002, R100003 and so on. Any suggestions as to how best create that?

    Thanks

    What you're describing can be achieved by using the Unique ID Widget.

    To get a better understanding on how to use it, refer to the guide I'm linking below.
