Display conditions query - display if field is empty

Users

Hi,

I'm very new to using Commcare and would like to know how I can display a
field only if a preceding field is blank?

Thanks in advance,

Adam

Hi Adam. Let's assume that the preceding field you are talking about has a
question ID of "my_first_question". Then you would want to enter in the
display condition of the next question:

/data/my_first_question = ''

Empty quotes indicates a blank field in CommCare, so here we are checking
whether the question value is equal to a blank value.

Since I'm sure you will come across many questions like this as you start
to use CommCare, I would suggest reading through this page and some of the
resources linked from it:
Common Logic and Calculations - CommCare Public - CommCare Public.
In particular, the sections on display conditions, validation conditions,
and calculation conditions will be a very good introduction to all of the
capabilities that CommCare's form builder provides.

Cheers,
Aliza
