Please suggest,

  • how do I stop / warn user from submitting duplicate data?
  • name each record instance uniquely

Adding an instanceID to the form will help with de-duplicating data. I
generally use something like this...

Before posting, search the group or the web. There are several answers to
these questions on the group.
Keep in mind that there are 100's of people on this list that have to
advance through each e-mail.

Start with 'uuid'

@yanokwa I suspect my concern, though related, may be a bit different. Occasionally I find submissions are duplicated (including instance ID).

Any way to avoid this? I use Google Sheets

The docs note that "Under certain failure conditions, the downstream service can receive multiple copies of a given submission. This is known, expected, behavior." I think this may be what's happening in your situation.

Ah, ok. Not a major problem yet; just requires some regular data cleanup before analysis. Thanks @danbjoseph
