Jay is correct. Some previewing in the software is intended to preview a single question, so it will not always show interactions that span multiple questions such as Not Applicable. The checkboxes should show up in Test Survey.
Although Not Applicable: Per Variable supports all standard grid and semantic diff questions, it may require modifications to work with a custom grid like Sliders. The first change we'll need to make is to set all rows in the grid question to not require a response.
Next, locate the function "updateNotApplicableVariable" in Not Applicable's footer. Replace that function with this:
function updateNotApplicableVariable(baseQuestion, naQuestion, name, bln) {
var regex = new RegExp('^' + naQuestion + '_([0-9]+)$');
var match = name.match(regex);
if (match) {
var item = Number(match[1]);
var input = $('#' + baseQuestion + '_r' + item + '_c1');
var slider = $(input).siblings('.slider');
if (bln) {
$(input).val('');
$(slider).slider('value', 0);
$(slider).find('.sliderHandle').text('');
$(slider).slider('disable');
}
else {
$(slider).slider('enable');
}
}
}
