use date from a previous field

[Michelle R]

Hello,

I am struggling with a probably simple issue... 

I have question that asks for the date when the patient was leaving the hospital ("hospitalisation_end").

Following that question I ask for the date of the isolation end ("isolation_end"). I would like to have a prefilled date which is the one already filled out for the first question. It can be changed if it differs.

I wanted to use the @DEFAULT action Tag but it somehow doesn't work: @DEFAULT:"[hospitalisation_end]". What is the problem?

Thank you for your support!

Michelle
