Hi @designfij, thanks for reaching out.

This topic is discussed elsewhere, here is a good post to take a look at:

> [@Stop Duplicate Entry](https://community.thunkable.com/t/stop-duplicate-entry/2175034):

> Hi, I want to prevent user to enter duplicate entry. I have two criteria. First if user id and date (given by user) match database(google sheet) and second if both user id & date are in same row. If data match and in same row that means data already submitted and user gets alert “Data already exists.” If not updated database.
