Please can someone advise if it is possible to determine if a select one item is selected or not. I have seen several examples of checking if a particular value is selected, but no way of checking if something is simply selected or not.
Thanks
You want a *require *constraint of TRUE -- this requires that the user
answer the question and not leave it blank.
Without it being required, you cannot ensure that the question is ever
answered.
If any field is not answered (left blank), the constraint on that field
will not be evaluated.
See http://opendatakit.org/help/form-design/binding/ for the list of
available functions.
Once it is required to have a value, you can count the number of choices
that were selected (e.g., for a multi-select) via:
count-selected(${mymultichoice})

Is there anyway to feedback to the individual which question is not completed, rather than just the standard message?
Hi Mitch,

is it possible to use the count-selected function on yes or no question? My
use scenario is a calculation of yes on the PHQ9 and determining the cut
off based on the number of yes's
Thanks and Regards

Ronald,
count-selected() only works on a single multi-choice prompt.
If you wish to count how many yes values you have across your form,
use something like this on the node you want the value stored in.
