it would probably be easiest to use a cloud variable for this.

Hi, @sakshamgoyal4031! 👋
This idea must help you -
- Setup Airtable in Thunkable, and create a column in the database.
- Whenever you click the button, generate a random no., and check weather it’s present in the database.
- If it’s present, then generate another no. because the previous no. is already present/used.
- When a new no. is generated, use it your way, and add it to the Airtable column.
Thanks! 😊
**P.S.** This method is not that much efficient, because it only checks the original no. - not the new one. I’ll come up with an efficient method soon. **This doesn’t mean that you can’t use this method.**

> Hi. please see this there is a side navigator. pull it out and go to the screen “cloud counting” I find cloud variables much easier to work with than firebase, but either would work for this use case
