Hi Odk community need a support from you guys.

So we need 3 conditions here to be met:

1. not selected that there was no door and selected that the frame was used for the door;
2. not selected that there was no roof and selected that the frame was used for the roof;
3. not selected a response option and selected "no"

recently i did this one "not(selected(${lat\_door},'no') and selected(., 'yes\_door')) and not(selected(., 'no') and not(selected(${lat\_roof},'no') and selected(., 'yes\_roof') and count-selected(.) \> 1))"

but its not working.  
your help will be really apricated.  
thanks

That is close. The first two conditions are correct:

`not(selected(${lat_door},'no') and selected(., 'yes_door')) and not(selected(., 'no') and not(selected(${lat_roof},'no')`

The third and final condition should be `not(selected(., 'no') and count-selected(.) > 1)`, so that it is not the case that "No" is selected and there is more than one item selected. All together, it is:

```auto
not(selected(${lat_door},'no') and selected(., 'yes_door')) and not(selected(., 'no') and not(selected(${lat_roof},'no') and not(selected(., 'no') and count-selected(.) > 1)

```
