Multiple selection validation

Support
1

Hi Yaw?
I want to hinder selection of a 'none' choice option and other options in
the list. The other options are names of RH organizations. So one can only
select multipe organization's without selecting none.

I tried;
'Constraint'
not (selected., '0') or selected(., '1') or selected (., '2') or
selected(., '3') or selected(., '4') or selected(., '5') or selected(.,
'99'))

0 is none 1/5 Are different organizations and 99 is other specify.

Thanks in advance.

Hi Yaw?
Thanks for the response. It works, though I have used >=2.
What is the difference in not(selected(.,'0') and count-selected(.) > 1)
when >1 or >2 is used?

I would also like to share something I have been working on.

So I wanted to make a multiple choice validation for a question about
source of IUCD with following choices.

  1. Facility doesn't offer IUCD.

  2. Government Medical stores.

  3. NGO providers.

  4. Wholesaler distributor.

  5. Drug factory.

  6. Registered pharmacy.

  7. General wholesaler.

  8. Don't Know.

  9. Facility has never stocked IUCD.

The challenge is to restrict a selection of Choice 1, 8 and 9 as a
combination. I also wanted to restrict a selection of 1, 8, 9 as a
combination with any other choice. In short only single select 1,8,9 if 1
or 8 or 9 is selected.

After playing around with a suggestion from Yaw, I succeeded;

"not(selected(., '1') and count-selected(.)>=2) and not(selected(., '8')
and count-selected(.)>=2) and not(selected(., '9') and
count-selected(.)>=2)"

I hope this will help someone who will need it.

Louis,

count-selected() counts the number of selected items in the prompt. So

X is if you want the number of selected things greater than X
