    Hi John,

    Thanks for reaching out to us for help. The unique ID widget should actually work how you expected it. If you've set it as 4 digits, it should always return a 4 digit value. If you're working on your Job Completion Worksheet form, I cloned your form and the unique ID widget was indeed set up to 4 digits, but the current index is 23 and that could be the reason why it's now following the correct incremental value.

    Looking at your form, it seems like you're trying something out. If you can provide us with more details about what you're trying to do, we can check it for you.

    Let us know if you have any other questions.
