It is to generate a protocol number for each customer's response?

I put together a menu olline want when my client make your request the menu to create a send code is like ?

If I understand correctly, you want to generate a random number code in the form each time a user makes a submission? If that is so, I believe the Random Value Generator widget is suitable for your requirement. This widget automatically generates a random number every time the form is opened.

You can also use the Unique ID widget if you want to generate a number that is in sequence. This widget will automatically increase the number by an increment for every submission received.

Here's a guide on How to Add a Widget to your Form?

If you need further assistance, please let us know.
