Checkboxes

Development
1

hi all,

i have a field with 8 checkboxes...the first is "none", second is "HIV",
third is "Cancer", and so on..i would want "none" to be selected if
none of the other 7 are selected; the other 7 can be selected together BUT
NOT with the "none" option. Either* *the *"none" option is by its
self, or the others can be selected together if not one of them. *The
following *constraint *code works for just two options but not more:

WORKING CODE: * not(selected(., 'None') and selected(., 'HIV'))*

CODE NOT WORKING: not(selected(., 'None') and selected(., 'HIV') and
selected(., 'Cancer') and ......)

Please help.

Thank you in advance

You should be able to do the following so as to not have to type out every
node each time, too:
not(selected(., 'None') and count-selected(.) > 1)
