Defaults in dates

How can I make a specific date appear while entering date? Or make a previously entered date appear while entering? For example, suppose there are two questions; 1) Enter your date of birth. 2) Enter the date you're vaccinated with BCG. These two dates are likely to be same. So, is there any way so that I can make the date I entered in Q1 appear by default in Q2 while entering data in ODK collect? I tried using default column and put ${dob} (for example) in the date_BCG row, but it didn't seem to work.

Hi @rajanpaudel
We're glad you're here. When you get a chance, please introduce yourself on this forum thread. I'd also encourage you to add a real picture as your avatar because it helps build community!

You need to use Dynamic defaults to solve your problem. There is a clear sample in the documentation so I believe you should be able to do the same with your form.
