I have an app which requires the user to key in a proposed price, and any amount which they enter outside of a certain range will show “Invalid input: Price outside of range.” Is there any way to do this with Stacker? By the way our database is linked to Airtable.

Example: User enters $100 but the range for input is $10 (min) to $50 (max). User would then not be able to save the data and a prompt will show up.

Hi @Gim

This is currently not possible to do out of the box, however it does look like some of [our experts](https://www.stackerhq.com/stacker-experts) have managed to do this with custom JS.

You may want to reach out to them to see whether you are able to get some more information on how this is implemented.
