Constraint on a multiple choice question

Support
1

Dear all,

I hope you are well.

I am wondering if I can put a constraint on a multiple choice question. I already tried the solution here https://groups.google.com/forum/#!msg/opendatakit/hHY0ngwuenA/h-mRzBbuWngJ

However it did not work for me.

I have a basic example but my real question includes more choices:
survey sheet

type name label
select_multiple water_sources hh_water_source Source of water

choices sheet

list name name label
water_sources house_tap Household tap
water_sources private_tap Private tap in yard
water_sources nothing nothing

If people choose House hold tap and Private tap in yard (or any other combination given that my original list has more options) I want them NOT to be able to select nothing. If people select nothing I want them NOT to be able to select Household tap and Private tap in yard.

I have attached the form if it will help you.

Best wishes and thank you for your help

Using XLSForm:

(1) on the choices sheet, add extra columns to your choices with your
different group restrictions.
(2) on your survey sheet, under the choice_filter column, specify a filter
predicate that will select the set of choices you want to show.

I.e., choices:

list_name name label groupset
my_choices v1 label1 grp1
my_choices v2 label2 grp1
my_choices v3 label3 grp2
my_choices v4 label4 grp2

And on your sheet

type ... choice_filter
select my_choices ... groupset='grp2'

An example of this is here:

This is part of the Cascading Selects feature.
