ODK: Select Multiple with NONE or N/A as a Choice

Development
1

Hello Community,

I have a scenario where a question is a Multiselect with the following choices as an example:

Choices: A,B,C,D,N/A

Users can select more than on choice e.g. A & C, however when the user wants to add another choice let say selects N/A then this action will unselect the choices A&C.

Problem: N/A cannot be selected if another choice is selected. If N/A is selected, only N/A should be allowed.

Please assist.

Regards,

Samuel.

Samuel,

Use a constraint where if n/a is selected, then count-selected(.) has to be 1.

Thanks in advance
