Hello
As shown above, I have a event form where I register participant information.
Now I want Age to be calculated from Date of birth field and directly put below the data of birth field. How do I do it ??

Thank you @Eyuel_Nigussie for posting.

You can simply do this by using program rules. You can use the function d2:yearsBetween which will produce the number of years between the date of birth and the current date.

Here is a quick explanation about the d2:yearsBetween function:

Hi @Eyuel_Nigussie you will need to create another attribute to have age as calculated value from date of birth as indicated by @hanin.saadah Hanin

@Eyuel_Nigussie

It actually depends on the place of the field. If it’s in the registration page so it’s a Tracked Entity Attribute. If it’s inside the stage so it’ll be a Data Element.

Is the posted picture above from Tracker stage or the registration page?

Yes indeed it is in the event tracker stage’s form.
