Calculate Age field is not showing in Form preview

Hi @maruf,

I don’t see a note question type that should display the calculated age in your xlsform. You could do it as shown in the image below:

Also please be informed that calculate question lets you evaluate complex expressions, storing the values for later use.

Besides, also please be informed that your syntax has some errors in it.
