Hi @Priyanka,

Basically, you need to put constraint, you can see in detail in here: Limiting Responses with Validation Criteria — KoboToolbox documentation

Here is a previous post about this:

How to limit the Date of birth to be at least 18 year ago

Maybe you could try this out as outlined in the image below: In the survey tab of your xlsform: [Image 1] Data entry screen as seen in Enketo: When a wrong entry is made [Image 2] Data entry screen as seen in Enketo: When a correct entry is made [Image 3] Reference xlsform: Calculate Age.xlsx (9.7 KB)

If you need further help, don’t hesitate to ask.
Best,
