I have a checklist which includes these two options:
- None (Choice Value = 'services_none'
and
- Don't know (Choice Value = 'services_unknown')
plus other options
If either one of these is selected then I want to validate to make sure no
other item is selected.
I've tried various bits of syntax but can't seem to get the logic right.
Currently I have the following in the Validation Field:
(. = selected(.,'services_none') and count-selected(.) > 1) or (. =
selected(.,'services_unknown') and count-selected(.) > 1)
But this isn't working.
Guidance would be gratefully received.

Hi Simon,
"selected(.,'services_none')" returns a boolean value so ". selected(.,
'services_none')" is not (I think) what you want. Try:
not(selected(.,'services_none') and count-selected(.) > 1) and not
(selected(.,'services_unknown')
and count-selected(.) > 1)
or simplifying:
not( (count-selected(1) > 1) and (selected(.,'services_none') or
selected(.,'services_unknown')
) )
(Syntax might be imperfect)
Cheers,
Will
