1. If you want toforce for 2 item to be dragged to group. Than you can add validation on right in Must select for Atleast=2 and Nomorethan=2. If any one drag less than 2 it will display error message "Please answer at least 2 choice(s)."

You can also popup question, For this you have to create a new question with Yes No. And have to add display logic like if only one is grouped or None is grouped. And than if someone click yes you can go further.



You have to add these two questions (group and rank , are you sure...) in seperate block.



For No: add same block where you have main question group and rank in survey flow again add this block in branch for No in "Are you sure...?"

Hello @LaurenK ,



Pick,Group and questions do not have Request Response option.

Try something like this!

Note you will need to use CSS to style CustomButton to match your themes NextButton.



Qualtrics.SurveyEngine.addOnReady(function()

{

const numberPerGroup = 2;

const errorMessage = 'Not every group has 2 elements, are you sure you want to continue?';

const that = this;

this.hideNextButton();

var btn = jQuery('<input id="CustomButton" class="NextButton Button" title=" >> " type="button" name="NextButton" value=" >> " aria-label="Next">')

jQuery('#Buttons').append(btn);

jQuery('#CustomButton').on('click', function(){

let passing = true

const groups = jQuery('.Group').map(function(){

return jQuery(this).find('ul');

}).map(function(){

return jQuery(this).map(function(){

return jQuery(this).find('li')

})

});



groups.each(function(){

if(jQuery(this)[0].length !== numberPerGroup){

passing = false

}

});



if(!passing){

let cont = confirm(errorMessage);

if(cont){

that.clickNextButton();

}

}else{

that.clickNextButton();

}

});

});
